Jim Barksdale, the CEO who navigated Netscape through the browser wars, told his board something that most business strategists still haven't fully absorbed: "There are only two ways to make money in business: one is to bundle; the other is to unbundle." The statement sounds reductive. It is not. Nearly every strategic move in modern business — every product launch, every acquisition, every startup pitch — reduces to one of these two plays. Bundle disparate things together into a package worth more than the sum of its parts. Or rip a bundle apart and do one piece better than the whole ever could.
The newspaper was one of the great bundles of the twentieth century. A single daily delivery contained national news, local news, sports scores, weather forecasts, stock prices, classified ads, job listings, personals, obituaries, comics, and coupons. The content had nothing in common except the economics of printing and distribution — it was cheaper to deliver everything together than to deliver each section separately. Craigslist attacked the classifieds. Indeed attacked the job listings. Zillow attacked real estate listings. Tinder attacked the personals. ESPN.com attacked the sports scores. Weather.com attacked the forecast. The newspaper didn't die because people stopped wanting news. It died because the internet collapsed the distribution cost that justified the bundle, and a dozen startups unbundled it piece by piece — each doing one thing better than a section of newsprint ever could.
Cable television ran the same arc a decade later. The cable bundle — 200 channels for $120/month — was an economic marvel. The average household watched seventeen channels. But the bundle worked because it captured maximum consumer surplus: the sports fan paid $120 for ESPN. The movie fan paid $120 for HBO. The news junkie paid $120 for CNN. Each thought they were paying for "cable." Each was subsidising the channels they never watched. Netflix unbundled the movie component. Hulu unbundled next-day TV. YouTube unbundled short-form entertainment. ESPN+ unbundled sports. By 2024, the average American household subscribed to 4.7 streaming services at a combined cost exceeding $87/month — and the industry began rebundling. Disney+ launched a bundle with Hulu and ESPN+. Amazon folded streaming into Prime. Apple bundled TV+, Music, Arcade, and iCloud into Apple One. The cycle completed in fifteen years.
The music industry offers the cleanest demonstration. For decades, the album was the bundle — twelve tracks sold together for $15, even though most buyers wanted two or three songs. Apple's iTunes Store unbundled the album in 2003: $0.99 per track, buy only what you want. Album revenue collapsed 65% in a decade. Then Spotify rebundled: $9.99/month for access to every song ever recorded. The album was a bundle of tracks. iTunes was the unbundler. Spotify was the rebundler. Three business models, one cycle, each phase destroying the previous phase's economics while creating its own.
The pattern is fractal — it operates at every level of abstraction. Microsoft Office bundled word processing, spreadsheets, and presentations into a suite that captured the desktop. Google unbundled individual functions into free web apps. Microsoft rebundled with Microsoft 365, adding Teams, OneDrive, and cloud collaboration. At the corporate level, GE bundled aviation, healthcare, and energy into a conglomerate. The market punished the bundle with a conglomerate discount for a decade until GE broke itself into three focused companies in 2024 — corporate unbundling driven by the same logic that unbundled newspapers. The distribution economics that justified the bundle changed. The bundle followed.
Section 2
How to See It
The cycle reveals itself whenever the economics of distribution change. When distribution is expensive, bundling wins — because aggregating demand across products reduces the per-unit cost of reaching the customer. When distribution becomes cheap, unbundling wins — because specialists can reach the same customer without the overhead of carrying products they don't need. The signal is not the product. It is the distribution cost. Every time a technology collapses the cost of reaching customers, expect the existing bundles to be dismantled. Every time customer acquisition costs rise, expect the pieces to be reassembled.
You're seeing Bundling and Unbundling when a product that combines multiple offerings faces competition from a focused competitor doing one piece better — or when several standalone products merge into a single subscription because the combined value exceeds what any individual component could charge alone.
Technology
You're seeing Bundling and Unbundling when Microsoft sells Office as a suite — Word, Excel, PowerPoint, Outlook, Teams — for a single subscription price. No user needs all the applications. But the bundle captures maximum willingness to pay: the writer pays $12.99/month for Word. The analyst pays $12.99/month for Excel. The manager pays $12.99/month for Teams. Each gets the full suite. Google attempted to unbundle with free individual tools — Docs, Sheets, Slides — but the bundle held because enterprise switching costs and Microsoft's distribution advantages made the unbundled alternative insufficient for most organisations. The bundle survived not because every component was best-in-class but because the aggregated value exceeded the price, and switching the entire workflow was more costly than accepting individual-component weakness.
Media
You're seeing Bundling and Unbundling when streaming services that originally unbundled cable begin adding live sports, news, and ad tiers — reassembling the cable bundle under new branding. Netflix adding NFL games on Christmas Day. Amazon streaming Thursday Night Football. Apple securing Major League Soccer. Each move adds a component that cable used to bundle. The reconvergence is not coincidence. Subscriber growth slowed once the easy unbundling gains were captured, and the only remaining path to growth was expanding the bundle — the same logic that built cable in the first place.
Financial Services
You're seeing Bundling and Unbundling when fintech startups attack individual banking functions — Venmo for payments, Robinhood for trading, SoFi for student loans, Affirm for credit. The traditional bank is a bundle: checking, savings, lending, payments, investing, insurance, and advisory all packaged under one roof with one relationship. Each fintech unbundled one function and delivered it with superior UX and lower fees. The banks' response was predictable: rebundle. JPMorgan Chase now offers a super-app combining banking, investing, rewards, and financial planning — a digital rebundle designed to recapture the customer relationship that fintechs fractured.
Investing
You're seeing Bundling and Unbundling when a conglomerate trades at a discount to the sum of its parts. General Electric bundled aviation, healthcare, energy, and financial services under one corporate umbrella for decades. The market consistently valued the bundle at less than the individual divisions would command independently — the "conglomerate discount." GE's breakup into three separate companies in 2024 was a corporate unbundling: investors valued the pieces more than the whole because the synergies that justified the bundle had eroded while the complexity costs had compounded. The market was telling GE what Barksdale already knew: when the bundle's overhead exceeds its synergies, the unbundlers win.
Section 3
How to Use It
The strategic question is never "should I bundle or unbundle?" in the abstract. It is "where in the cycle is my market right now?" — because the answer determines whether the next move creates value or destroys it.
Decision filter
"Ask: does the current bundle serve every customer segment well, or does it serve the average customer adequately while overserving some and underserving others? If the former, the bundle is defensible. If the latter, an unbundler will find the underserved segment and pick it off — and the segment they pick will be the one generating most of the bundle's profit margin."
As a founder
If you are attacking an incumbent, unbundle. Find the single function inside the incumbent's bundle that customers value most and that the bundle delivers worst — because the bundle optimises for breadth, not depth. Build the best version of that one function and price it below the bundle's effective per-function cost. Slack unbundled internal communication from the enterprise productivity bundle. Zoom unbundled video conferencing from Cisco's collaboration suite. Stripe unbundled payments from the banking bundle. Each won by doing one thing with an intensity that a bundled offering could never match.
If you are defending a position, rebundle. The startup that wins by unbundling one function will eventually need to expand — because single-function businesses face margin compression and acquisition cost pressure. The response is to bundle adjacent functions that share the same customer, creating switching costs and increasing willingness to pay. Shopify unbundled e-commerce from enterprise software, then rebundled payments, shipping, lending, and email marketing into a platform that is harder to leave with each added component.
As an investor
Track where markets sit in the cycle. Industries dominated by large bundles with declining customer satisfaction are ripe for unbundling — and the unbundlers will capture disproportionate value in the early phase. Industries fragmented across dozens of point solutions with rising customer acquisition costs are ripe for rebundling — and the aggregator that assembles the right bundle will generate the next platform.
The valuation signal: unbundlers command premium multiples early (because they're growing fast on a single metric) and face compression later (because single-product businesses hit ceilings). Rebundlers command lower multiples early (because bundling looks like unfocused diversification) and premium multiples later (because the bundle creates retention and pricing power that compound). Time your entry to the cycle phase.
As a decision-maker
Audit your product portfolio through the bundling lens. If you offer a suite of products, ask which components customers would pay for independently and which they tolerate because they come with the bundle. The components they tolerate are your vulnerability — because an unbundler will offer customers the components they want without the components they don't. The components they would pay for independently are your leverage — because those are the products around which you should build the next iteration of the bundle.
The most dangerous position: a bundle where no single component is best-in-class. Microsoft survived unbundling attempts because Excel and Outlook are individually defensible products. A bundle of mediocre components is a bundle waiting to be dismantled.
Common misapplication: Believing that bundling is always the incumbent's play and unbundling is always the startup's play. Amazon is the most valuable startup of the past thirty years, and its core strategy is bundling — aggregating shipping, streaming, reading, and cloud services into Prime. Netflix started as an unbundler (DVD-by-mail versus the video store bundle) and became a rebundler (original content + licensed content + games + live events in one subscription).
Second misapplication: Assuming that the unbundled version is always superior. Unbundling creates value when the bundle's components have heterogeneous demand — when different customers want different pieces. When demand is homogeneous — when most customers want most of the bundle — unbundling destroys value by forcing customers to assemble and manage multiple point solutions. The enterprise SaaS buyer drowning in thirty different tools with thirty different logins, billing systems, and support teams is living the failure mode of unbundling taken too far.
Third misapplication: Ignoring the rebundling phase. Every unbundling wave creates fragmentation, and fragmentation creates the opportunity for the next bundle. The founder who unbundles successfully and then fails to rebundle adjacent functions will be outflanked by the competitor who does. Unbundling is a growth strategy. Rebundling is a retention strategy. You need both to build a durable business.

The Mechanism
Section 5
Founders & Leaders in Action
Both leaders below mastered both sides of the cycle — not because they read about bundling theory, but because they recognised that the same customer could be served by dismantling one package and assembling another. One unbundled the album and rebundled the device. The other unbundled retail and rebundled everything into a single membership.
What unites them is the refusal to be categorised as either a bundler or an unbundler. Both understood that the strategic question is never "bundle or unbundle" but "what should be bundled together now, given today's distribution economics?" — and both were willing to cannibalise their own unbundling victories to capture the rebundling opportunity that followed.
Jobs executed the most elegant bundle-unbundle-rebundle sequence in business history. In 2001, the iPod bundled a thousand songs into a single device — replacing the portable CD player, the Walkman, and the home stereo as the primary music interface. In 2003, the iTunes Store unbundled the album: $0.99 per track, buy only what you want. The record labels screamed. Consumers celebrated. Album revenue collapsed 65% in a decade, but Apple captured the margin that the physical distribution chain had previously consumed. Then, in 2007, Jobs rebundled at a higher level of abstraction. The iPhone was not a phone. It was a bundle of devices — phone, iPod, camera, web browser, GPS, calculator, alarm clock, flashlight, calendar, and notebook — compressed into a single object. Each of those was a standalone product category that the iPhone absorbed. Garmin's stock fell 85% from its 2007 peak. Point-and-shoot camera sales dropped 97% by 2023. The iPod itself was discontinued in 2022, consumed by the bundle that created it. Jobs understood that unbundling creates the opportunity and rebundling captures the value. iTunes unbundled the album to drive iPod adoption. The iPhone bundled everything to create the most valuable product in history.
Bezos built the most valuable bundle in consumer commerce — and he did it by adding one component at a time until the aggregate value made leaving irrational. Amazon Prime launched in 2005 as a shipping bundle: $79/year for unlimited two-day delivery. The economics were simple — frequent shoppers saved on shipping costs, and the prepaid commitment increased purchase frequency by an estimated 2x. Then Bezos started adding. Prime Video in 2011. Prime Music in 2014. Prime Reading and Prime Photos in 2016. Prime Gaming in 2020. Prescription discounts, grocery delivery, and exclusive deals followed. By 2024, Prime cost $139/year and included a constellation of services that would cost over $1,000 annually if purchased separately. The bundle's genius was not any single component — Netflix had better streaming, Spotify had better music, Google Photos had better storage. The genius was that no customer subscribed for one reason, which meant no competitor could unbundle a single component and threaten the whole. The customer who signed up for shipping stayed for streaming. The customer who stayed for streaming discovered grocery delivery. Each component strengthened every other component through shared acquisition cost and compounding habit formation. Amazon spent an estimated $16.6 billion on Prime Video content in 2023 — not to compete with Netflix on streaming but to reduce Prime churn, which retained millions of subscribers whose primary value was the shopping flywheel. The content was not the product. The bundle was the product.
Section 6
Visual Explanation
The cycle is driven by a single variable: distribution cost. When it is expensive to reach customers, bundling wins because aggregating demand across products reduces the per-customer cost of distribution. When distribution becomes cheap — as every major platform shift makes it — unbundling wins because specialists can reach the same customers without the overhead of carrying unrelated products. The trigger for each phase is not a strategic insight. It is an economic shift. The strategist's job is to recognise which phase the market has entered and move before competitors do. The companies that time the transition — unbundling the old model before the incumbent recognises the threat, rebundling the fragments before the market saturates — capture disproportionate value. The companies that misread the phase build bundles nobody wants or unbundle products nobody asked to separate.
Section 7
Connected Models
Bundling and unbundling is a meta-strategy — it operates above the level of individual products and reshapes entire markets. The connected models below describe the forces that make bundling powerful, the dynamics that trigger unbundling, and the downstream effects that each phase produces.
The reinforcing connections show how bundling compounds through platforms, distribution advantages, and network effects — each making the bundle stickier and harder to attack. The tension connection reveals the force that breaks bundles apart. The leads-to connections trace how the cycle's output — the unbundled components and the strategic logic behind them — manifests in adjacent frameworks. Understanding these connections reveals why the cycle repeats and why timing — not just direction — determines whether bundling or unbundling captures value.
Reinforces
Platform Business Model
Platforms are bundles by nature. A platform aggregates supply, demand, tools, and services into a single environment — and the value of the platform increases with the number of components it bundles. Apple's iOS bundles the App Store, iMessage, iCloud, Apple Pay, and health tracking into a platform that is more valuable than any individual component. Amazon bundles marketplace, logistics, payments, and advertising into a platform that third-party sellers depend on entirely. The reinforcement is structural: bundling more services into the platform increases switching costs, which strengthens the platform's position, which enables further bundling. The most valuable platforms are the ones that have bundled so many functions that unbundling any single one would require the user to abandon the entire ecosystem.
Tension
Disruptive Innovation
Disruption is unbundling's sharpest weapon. Clayton Christensen's framework describes how a simpler, cheaper product enters at the low end of a market and gradually improves until it displaces the incumbent. The mechanism is unbundling: the disruptor strips away the features that the mainstream customer doesn't use, delivers the core function at a lower price, and builds upward. Netflix disrupted cable by unbundling on-demand content from the channel bundle. Google Docs disrupted Office by unbundling basic document editing from the feature-heavy suite. The tension: bundling is the incumbent's defence against disruption, because the bundle creates switching costs and surplus capture that make the disruptor's unbundled offering feel incomplete. The two forces exist in permanent opposition — each creating the conditions that empower the other.

One Key Quote
"There are only two ways to make money in business: one is to bundle; the other is to unbundle."
— Jim Barksdale, CEO of Netscape, board meeting (c. 1995)
Barksdale delivered this line to a room of Netscape board members that included Marc Andreessen, John Doerr, and a group of technologists building the browser that would unbundle more industries than any single technology since the printing press. The statement's power is its compression. Decades of academic bundling theory, centuries of commercial practice, and every strategic playbook in technology reduce to a binary choice. Not because business is simple — but because the cycle between aggregation and disaggregation is the deepest structural rhythm in commerce.
Every industry oscillates between the two states. Music went from bundled albums to unbundled singles to rebundled subscriptions. Television went from bundled cable to unbundled streaming to rebundled super-apps. Banking went from bundled full-service to unbundled fintech to rebundled super-apps. The cycle does not end because neither state is stable. Bundles attract unbundlers who spot overserved customers. Unbundled markets attract rebundlers who spot fragmented customers reassembling their own bundles manually. Barksdale's insight is not that one strategy is better. It is that the two strategies are the only strategies — and the winner at any moment is determined by where the market sits in the cycle.
The corollary that Barksdale left implicit: the same company can play both sides at different altitudes. Apple unbundled the album while bundling the device. Amazon unbundled retail while bundling membership. The operators who build generational companies are the ones who recognise which level of abstraction to bundle at and which to unbundle — simultaneously.
Section 9
Analyst's Take
Faster Than Normal — Editorial View
The bundling-unbundling cycle is the most reliable pattern in technology, and the most reliably mistimed. Founders launch unbundling plays five years after the optimal window because they mistake a mature bundle for a vulnerable one. Investors fund rebundling plays before the market has fragmented enough for the rebundle to feel necessary. The cycle is obvious in retrospect. In real time, the question is always whether the current bundle is weakening or whether it just looks like it should be.
The diagnostic I use: customer workaround intensity. When customers are building their own bundles by stitching together three or four point solutions with Zapier and duct tape, the market is ready for a rebundle. When customers are paying for a suite but only logging into one application, the market is ready for an unbundle. The workaround reveals the gap between what the market offers and what customers actually need. Every manual integration is an unbundling opportunity. Every tool-switching headache is a bundling opportunity.
The biggest misread in the current market is treating AI as purely an unbundling force. AI will unbundle knowledge work — replacing bundled professional services with specific, narrow AI tools that do one function better than a generalist. But AI will also enable the most powerful rebundling in history. A single AI assistant that handles email, scheduling, research, writing, analysis, and customer service is a bundle of ten SaaS products compressed into one interface. The startups building single-function AI tools are the unbundlers. The platform that integrates those functions into a coherent workflow will be the rebundler. Barksdale's cycle is about to run at a speed we haven't seen before — and the winners will be the ones who read the phase correctly.
The meta-lesson: the founders who build lasting companies are the ones who execute both sides of the cycle. Jobs unbundled the album and rebundled the device. Bezos unbundled retail and rebundled everything into Prime. Hastings unbundled cable and is rebundling entertainment. The one-move founders — the pure unbundlers who never rebundle — build features, not companies. The cycle rewards the operators who can play both directions.
One more pattern worth flagging: the rebundle always looks different from the original bundle. The streaming bundle does not look like the cable bundle — no contracts, no hardware, no channel numbers. Amazon Prime does not look like a department store — no physical location, no sales staff, no browsing aisles. The rebundle inherits the economic logic of the original (aggregate diverse demand, reduce per-customer cost) but adopts the distribution advantages of the era that killed it. The founders who try to rebuild the old bundle with new technology fail. The founders who build a new bundle native to the current distribution paradigm win.
Section 10
Test Yourself
The scenarios below test whether you can identify where a market sits in the bundling-unbundling cycle and predict which strategic direction captures value. The key diagnostic: is the bundle creating value for customers by aggregating diverse needs — or is it creating frustration by forcing customers to pay for components they don't want? The answer tells you which phase the market is entering.
The most common analytical error is assuming the current state is permanent. Analysts who declared "the bundle is dead" in 2015 when streaming was fragmenting cable missed the rebundling that followed. Analysts who declared "the suite will never be disrupted" in 2010 missed the unbundling of enterprise software into point solutions. Read the customer behaviour, not the narrative. The cycle does not care about your thesis.
Pay particular attention to the scenarios where the answer is counterintuitive — where a bundle that appears vulnerable is actually defensible, or where an unbundling that looks inevitable is actually premature.
Is the cycle pointing toward bundling or unbundling?
Scenario 1
A large enterprise software company sells a suite of twelve integrated tools for $300/user/month. Customer surveys reveal that the average customer actively uses three tools. A startup launches one of those twelve tools as a standalone product with superior UX, priced at $30/user/month. Within eighteen months, the startup captures 15% of the enterprise company's customers for that specific function.
Scenario 2
A mid-size company uses seven different SaaS tools for marketing: email (Mailchimp), social scheduling (Buffer), analytics (Google Analytics), CRM (HubSpot), landing pages (Unbounce), SEO (Ahrefs), and advertising (Google Ads). Each team member manages three to four logins, reconciles data across platforms manually, and spends roughly five hours per week on integration overhead. A new platform launches offering all seven functions in a single interface at a combined price 20% lower than the total of the individual tools.
Scenario 3
A streaming service bundles live sports, scripted dramas, reality TV, children's content, news, and documentaries for $22/month. Customer data shows that 73% of subscribers watch content from only one or two categories. A competitor launches a sports-only streaming service at $8/month, featuring the same leagues and better commentary. Within a year, the sports-only service has 4 million subscribers.

Top Resources
The literature on bundling and unbundling spans microeconomic theory, platform strategy, and media economics. Start with Shapiro and Varian for the foundational economics of why bundling works, move to Thompson for the modern application to technology platforms, and read Christensen for the disruption dynamics that trigger unbundling cycles. The academic work explains the mechanism. The applied work reveals the timing. Both are necessary — understanding why bundling works without understanding when it works produces strategy that is theoretically correct and practically mistimed.
The definitive economic treatment of bundling in information markets. Shapiro and Varian demonstrate why bundling becomes more powerful as marginal costs approach zero — the precise condition that defines digital goods. Their analysis of versioning, bundling, and pricing strategy provides the analytical framework for understanding why every major technology company gravitates toward the bundle and why unbundlers must overcome structural economic advantages, not just product quality deficits.
Thompson's Aggregation Theory is the most influential modern framework for understanding how internet-era platforms bundle distribution, and his ongoing analysis of media, technology, and platform dynamics provides real-time coverage of the bundling-unbundling cycle across every major industry. Essential reading includes his analysis of Netflix, the conservation of attractive profits, and how platforms aggregate supply and demand into bundles that previous-era economics could not support.
Christensen's disruption framework is the mechanics of unbundling expressed as competitive strategy. The pattern he identified — a simpler product enters at the low end and improves until it displaces the incumbent — is structurally identical to unbundling: strip the unnecessary features from the bundle, serve the underserved segment, and expand upward. Required for understanding why incumbents' bundles are vulnerable and which specific components the disruptor should target.
The comprehensive treatment of how platforms bundle services to create network effects, switching costs, and winner-take-all dynamics. Parker and Van Alstyne's analysis of platform governance and pricing explains why platform bundles are structurally more durable than product bundles — and why the unbundling of platforms requires a fundamentally different strategy than the unbundling of traditional businesses.
The foundational academic paper that formalised the economics of bundling. Adams and Yellen proved mathematically that a firm can increase profits by bundling goods with negatively correlated demand — even when some customers value individual components below their standalone price. The insight that bundling reduces variance in willingness to pay remains the theoretical foundation for every bundling strategy deployed in technology, media, and consumer markets today.
Bundling and Unbundling — The endless cycle where distribution economics determine whether aggregation or disaggregation captures more value.
Bundling is fundamentally a distribution strategy. The cable bundle existed because the cost of distributing 200 channels to a home was the same as distributing one — so the marginal cost of adding channels was near zero, and the marginal revenue was positive. Amazon Prime is a distribution bundle: the cost of shipping a package to a Prime member is largely fixed, so adding streaming, music, and reading costs Amazon relatively little while increasing the perceived value enough to justify the membership fee. Distribution economics determine whether bundling or unbundling is the dominant strategy at any moment. When distribution costs are high, bundle. When distribution costs collapse, specialists can distribute directly and the bundle loses its economic justification.
Reinforces
Network Effects
Bundling accelerates network effects by increasing adoption velocity. Amazon Prime's bundle of shipping, streaming, and shopping creates a flywheel: more Prime members attract more third-party sellers, more sellers increase product selection, more selection increases the value of Prime membership. Microsoft's bundle of Office, Windows, Teams, and Azure creates a similar dynamic: the more organisations use the bundle, the stronger the interoperability advantage, the higher the switching cost, the deeper the lock-in. Network effects make bundles stickier because each component's network reinforces every other component's network — creating a compounding advantage that unbundlers must overcome not one product at a time but all at once.
Leads-to
12 Standard Forms of Value
Unbundling reveals which forms of value customers actually care about — stripped of the packaging that bundling obscures. When the newspaper was unbundled, it became clear that readers valued convenience (weather apps), social connection (dating apps), and transaction facilitation (job boards) more than the editorial content that publishers assumed was the core product. Each unbundled piece maps to a distinct form of value from Josh Kaufman's framework. The strategic insight: bundling hides which components create value and which are passengers. Unbundling forces an honest reckoning. The components that survive unbundling intact are the ones delivering genuine, standalone value. The components that collapse without the bundle were subsidised by the ones that didn't.
Leads-to
[Freemium](/mental-models/freemium)
Freemium is unbundling applied to a single product: strip the product into a free core and premium extensions, then let the customer decide which components are worth paying for. Spotify's free tier unbundles the music listening experience — you get access to every song, but with ads, limited skips, and no offline playback. The premium tier rebundles the complete experience. Zoom's free tier unbundles basic video calling from the enterprise collaboration suite. The paid tiers rebundle recording, longer meetings, and admin controls. Freemium works when the free component is valuable enough to drive adoption and the premium components are valuable enough to drive conversion — the same economic logic that governs which bundles hold and which get dismantled.
