The Last Call
On June 13, 2025, at midnight UTC, the servers went dark. Microsoft retired Skype — the application that once connected 300 million monthly users, that verb-ified a technology, that made "Can you Skype me?" a universal idiom from São Paulo to Stockholm — and redirected its remaining users to Microsoft Teams. The shutdown did not produce outrage. It barely produced a shrug. By the time the plug was pulled, Skype's monthly active user count had cratered to roughly 36 million, a figure that would have been humiliating in 2012 and was merely melancholic in 2025. The product that introduced hundreds of millions of people to the possibility of free, global, real-time video communication — that was, for a luminous half-decade, the most important consumer application on the internet — had been reduced to a redirect notice and a migration wizard.
The number that explains Skype is not its peak user count, or its $8.5 billion acquisition price, or the 2 billion minutes of video and voice calls that once traversed its network on peak days. The number is
$0.00 — the price of a Skype-to-Skype call. That was the founding insight, the strategic weapon, and ultimately the trap.
Free communication was revolutionary when it launched in 2003. By 2015, it was table stakes. And between those two dates lies a story about what happens when a product becomes a category, a category becomes a commodity, and the company that created both fails to build a business on top of either.

What killed Skype was not one thing. It was an accumulation — a product architecture that couldn't scale to mobile, a series of owners who each misunderstood its value in different ways, a failure to monetize the attention it had captured, and the arrival of competitors who understood that communication was not a product but a feature embedded in a platform. Skype's story is the purest case study in tech history of the innovator's paradox: the company that creates a category and then gets swallowed by it.
Two Men in a Sauna
The founding mythology is Estonian and Scandinavian, which already distinguishes it from the Cupertino-or-Cambridge origin stories of its contemporaries. Niklas Zennström, a tall, restless Swede with a physics degree from Uppsala University and an MBA from the Stockholm School of Economics, had already proven he could build software that terrified industries. With his Danish partner Janus Friis — younger, more volatile, a high school dropout who'd taught himself programming and had a contrarian's instinct for picking fights with incumbents — Zennström had co-founded Kazaa, the peer-to-peer file-sharing application that succeeded Napster as the recording industry's nightmare. Kazaa used a decentralized architecture that made it almost impossible to shut down, and by 2003 it had been downloaded over 230 million times. It had also made Zennström and Friis the targets of lawsuits from every major record label. They needed a new venture. Preferably one that was legal.
The insight came from an Estonian software team. Ahti Heinla, Priit Kasesalu, and Jaan Tallinn — three Estonian developers who had built the backend architecture for Kazaa — saw that the same peer-to-peer technology that distributed music files could distribute voice packets. The key realization: if you could route voice traffic through a decentralized mesh of user computers rather than through centralized servers, you could bypass the entire telecom infrastructure. No switches. No trunk lines. No per-minute charges. The marginal cost of an additional call would approach zero.
Zennström and Friis incorporated Skype Technologies S.A. in Luxembourg in August 2003 — the legal domicile chosen for tax efficiency, the development team sitting in Tallinn, Estonia, the business operations eventually running from London. The first public beta launched on August 29, 2003, and within 24 hours it had drawn significant downloads. Within two days of launch, the client had been downloaded over 10,000 times. By the end of 2003, Skype had accumulated over one million registered users. By February 2004, the concurrent user count hit one million. By October 2004, it reached 100 million total downloads. The growth curve was not hockey-stick-shaped. It was vertical.
The whole point of Skype is that it makes communication free. We want to make the world's phone call.
The product worked because of three interlocking advantages. First, the peer-to-peer architecture meant Skype bore almost none of the infrastructure costs that burdened traditional telecom companies — users' own machines served as the network. Second, the call quality was genuinely superior to what most people experienced on landlines, partly because Skype used wideband audio codecs that sampled at 16 kHz, double the 8 kHz of the public switched telephone network (PSTN). Skype calls sounded better than phone calls. Third, the product was dead simple. Download, install, create a username, call. The interface was clean, almost conspicuously simple for its era — a green call button, a contact list, a search bar. Your grandmother could use it. Millions of grandmothers did.
The Free Call and the Paid Minute
The business model that Zennström and Friis constructed was a textbook example of what Chris Anderson would later popularize as "freemium" — though Skype was executing the strategy before the term existed. Skype-to-Skype calls were free. Forever. That was the hook, the network-effects accelerant, the thing that pulled 150 million registered users into the ecosystem by mid-2006.
The monetization came at the edges, where Skype's digital world intersected with the analog telephone network. SkypeOut — later rebranded Skype Credit — let users call landlines and mobile phones at rates that started around €0.017 per minute to the United States. These rates were typically 80–90% cheaper than incumbent international calling rates, which still commanded dollars-per-minute premiums for cross-border calls in 2004. SkypeIn gave users a local phone number in a chosen country, so that people on traditional phones could call them. Skype voicemail charged a small subscription fee. Later, Skype introduced subscription plans — unlimited calling to specific countries for a flat monthly fee, typically $2.99 to $13.99 per month.
The unit economics were elegant in theory. The free Skype-to-Skype calls cost almost nothing to carry, since the peer-to-peer architecture externalized infrastructure costs onto users. The paid calls to the PSTN required Skype to pay termination fees to telecom carriers, but Skype's rates were set high enough above those wholesale costs to generate meaningful margins. The conversion rate — the percentage of free users who paid for anything — hovered in the low single digits, but the absolute numbers were enormous because the free user base was so vast.

Skype Revenue Model (2005–2010)
How a free product extracted billions
| Revenue Stream | Mechanism | Est. Share of Revenue |
|---|
| SkypeOut / Skype Credit | Pay-per-minute calls to PSTN | ~60% |
| SkypeIn | Local phone number subscription | ~15% |
| Subscription Plans | Flat monthly fee for unlimited calling | ~15% |
| Skype Voicemail & Premium | Add-on subscriptions | ~5% |
| Hardware Licensing | Certified Skype phones & accessories | ~5% |
By 2008, Skype was generating approximately $550 million in annual revenue and had achieved EBITDA profitability. By 2010, the year before Microsoft acquired it, Skype reported revenue of approximately $860 million with 663 million registered users. The growth was real. The profitability was real. The problem — the one that would define the next fifteen years — was that Skype's revenue was almost entirely tied to the PSTN bridge. The free calls generated engagement. The paid calls generated revenue. And the paid calls were, by their nature, a transitional business — a toll bridge between the digital and analog worlds. As the analog world shrank, the toll bridge would shrink with it.
The eBay Detour
On September 12, 2005, eBay announced it would acquire Skype for $2.6 billion, with an additional $1.5 billion in potential earn-out payments tied to performance milestones. The deal was championed by eBay CEO
Meg Whitman, who argued that Skype would enhance buyer-seller communication on the eBay marketplace. The logic: if buyers and sellers could talk to each other in real time, trust would increase, transactions would accelerate, and eBay's marketplace velocity would benefit. Skype would be the communication layer of commerce.
The thesis was, to be charitable, imaginative. eBay's marketplace was a fundamentally asynchronous experience — buyers searched, bid, won, paid. The idea that they needed real-time voice communication with sellers ran counter to the platform's entire behavioral grammar. eBay buyers did not want to negotiate with a stranger in Shenzhen over a webcam. They wanted to click "Buy It Now."
Whitman's conviction was genuine but detached from user behavior. She had transformed eBay from a quirky auction site into a global marketplace, and she believed that communication technology would be the next strategic layer of e-commerce. She was not wrong about the future — social commerce and live-selling would validate versions of this thesis a decade later, on platforms like Taobao Live and TikTok Shop. She was wrong about the timing, wrong about the product fit, and wrong about eBay as the platform to execute it.
The earn-out milestones were missed. eBay wrote down $900 million of Skype's value in 2007. By 2009, the relationship was openly dysfunctional. In September 2009, eBay sold 65% of Skype to a private investor group led by Silver Lake Partners for approximately $2 billion, valuing the entire company at roughly $2.75 billion — barely above what eBay had paid four years earlier, and well below the $4.1 billion total consideration including the earn-out. eBay retained a 35% stake and eventually recognized a gain when Microsoft acquired Skype in 2011, but the eBay years represented something worse than a financial loss. They represented lost time.
During the four years under eBay, Skype's product development stagnated. The company was starved of the engineering resources it needed to rebuild its architecture for the coming mobile era. The peer-to-peer technology that had been its founding advantage was becoming a liability — it drained battery life on mobile devices, struggled with NAT traversal on cellular networks, and required one of the user's devices to be online at all times to serve as a "supernode" for routing calls. The mobile transition was visible by 2007, when the iPhone launched. Skype needed to be rebuilt from the ground up. Instead, it was managed as a subsidiary of an auction marketplace, its roadmap subordinated to integration experiments that never produced results.
The eBay relationship was a distraction. Skype needed to focus on being the best communication product in the world.
Supernode: The Architecture of a Revolution and Its Limits
To understand why Skype thrived and then couldn't adapt, you have to understand the supernode architecture. It was both Skype's most brilliant innovation and its most crippling technical debt.
In a traditional telecom network, calls are routed through centralized switches owned by the carrier. The carrier bears the capital cost of the infrastructure, amortizes it over decades, and charges customers per-minute fees to recover the investment. In Skype's peer-to-peer model, there were no central switches. Instead, user devices that met certain criteria — sufficient bandwidth, a public IP address, adequate processing power — were automatically promoted to "supernodes" that helped route calls for other users. The network was self-organizing. As more users joined, more supernodes became available, and the network's capacity scaled automatically. Skype bore almost zero marginal infrastructure cost for each additional user.
This was a work of genuine engineering elegance. Jaan Tallinn, who would later become one of the founders of the Centre for the Study of Existential Risk at Cambridge, co-designed a system that turned every user's computer into a piece of shared infrastructure. The Global Index, a distributed hash table, allowed any Skype client to locate any other user in the network without a central directory server. Call setup involved traversing a cascade of supernodes to find the callee, negotiate codecs, and establish a direct media stream — or, if direct connection was impossible due to firewalls or NAT, relay the call through intermediate supernodes.
The elegance masked a profound fragility. The supernode model assumed that users would have always-on desktop computers with stable internet connections. That assumption was approximately correct in 2003 and approximately wrong by 2010. The rise of laptops meant devices slept more often, reducing supernode availability. The rise of smartphones meant users were on cellular connections with aggressive NAT, battery constraints, and intermittent connectivity — conditions under which the peer-to-peer model degraded catastrophically. Calls dropped. Login times stretched to thirty seconds or more. The app drained batteries. Group calls, which required sophisticated multi-party routing through supernodes, were unreliable.
Microsoft, after acquiring Skype, recognized the problem and between 2012 and 2013 migrated the network from a pure peer-to-peer architecture to a hybrid model using dedicated Microsoft-hosted supernodes in data centers. This fixed the reliability problems but destroyed the economic advantage — Skype now bore the infrastructure costs of a centralized service, like every other communication platform, but without the revenue model to support it. The migration was necessary and fatal.
Eight Point Five Billion Dollars
On May 10, 2011, Microsoft CEO Steve Ballmer announced that Microsoft would acquire Skype for $8.5 billion in cash — the largest acquisition in Microsoft's history at that time. The price represented roughly 10x Skype's trailing revenue and a premium of approximately 200% over the $2.75 billion valuation from the Silver Lake deal just two years earlier. Silver Lake's consortium, which had invested roughly $2 billion for their 65% stake in 2009, walked away with approximately $5.5 billion — one of the most profitable private equity trades in tech history, achieved in barely 18 months of ownership.
Ballmer's case for the acquisition was characteristically expansive. Skype's 170 million connected users at the time of the deal would be integrated across Microsoft's product portfolio — Windows, Xbox, Outlook, the nascent Windows Phone platform, and the enterprise communication tools that would eventually become Teams. "Skype is a phenomenal product and brand," Ballmer declared. "Together we will create the future of real-time communications."
Skype is a phenomenal product and brand that is loved by hundreds of millions of people around the world.
The strategic logic was not insane. Microsoft lacked a credible consumer communication product. Windows Live Messenger had approximately 330 million active users but was losing relevance. Lync (later Skype for Business) served enterprises but was clunky and unloved. Google was investing heavily in Google Voice and Hangouts. Apple had launched FaceTime. Facebook was building Messenger. The real-time communication layer was becoming a key competitive surface, and Microsoft risked being locked out. $8.5 billion was, in this framing, the price of relevance.
The price was also, in another framing, the price of desperation. Microsoft under Ballmer had missed mobile — Windows Phone would never exceed 3.6% global smartphone market share — and was watching the consumer internet fracture into walled gardens controlled by Apple, Google, and Facebook. Skype was the one consumer internet property with genuine global scale that Microsoft could plausibly acquire. It was less a strategic choice than a strategic necessity born of strategic failure.

The Verb That Became a Vulnerability
For roughly three years after the Microsoft acquisition, Skype appeared to be executing. Monthly active users grew from approximately 170 million at acquisition to a peak of around 300 million by 2013–2014. Skype was pre-installed on Windows 8 devices. The Xbox integration made Skype the default video calling app on Microsoft's gaming console. Cross-platform availability was excellent — Windows, Mac, iOS, Android, Linux, even smart TVs.
But beneath the user metrics, the product was decaying. The migration from peer-to-peer to centralized infrastructure, completed by 2013, stabilized call quality but introduced new problems. The Skype desktop client, originally lightweight and fast, grew bloated under Microsoft's stewardship — feature additions piled on without coherent product vision. The mobile app was persistently inferior to competitors. Notifications were unreliable. Messages arrived out of order. Group video calls dropped. The app consumed disproportionate battery and storage. Each new update seemed to rearrange the interface without improving the experience.
The deeper problem was strategic. Skype had become a verb — "Skype me" — but verbing is not a moat. The technology that Skype had pioneered, real-time voice and video over IP, was being commoditized by open standards (WebRTC, released by Google as an open-source project in 2011) and embedded into every major platform. Apple built FaceTime directly into iOS and macOS, making video calling a zero-friction feature for the 1.5 billion Apple device installed base. Facebook integrated voice and video calling into Messenger, leveraging its 1.3 billion user social graph. Google built Hangouts into Gmail and then Android. WhatsApp added voice calling in 2015 and video calling in 2016, reaching users who had never owned a computer.
Each of these competitors had something Skype lacked: a platform or social graph that users were already inside. FaceTime lived in your contacts. Messenger lived in your Facebook relationships. WhatsApp lived in your phone number. Skype required you to know someone's Skype username, to download a separate application, to create an account, to add a contact — a series of friction steps that had been negligible when Skype was the only option and became intolerable when alternatives were one tap away.
The verb persisted long after the behavior had migrated. By 2016, "Skype me" increasingly meant "video call me using whatever app we both have." The brand had become generic — useful for cultural presence, useless for user retention.
The Enterprise Pivot That Wasn't
Microsoft's most consequential strategic error with Skype was not the bloated consumer app or the mobile failures. It was the confused handling of the enterprise opportunity.
When Microsoft acquired Skype, it already owned Lync — an enterprise unified communications platform that served as the backbone of voice, video, and instant messaging for corporate customers. The obvious question was: merge them. Microsoft attempted this in 2015, rebranding Lync as "Skype for Business." The name was meant to leverage Skype's consumer brand recognition to accelerate enterprise adoption. The execution was disastrous.
Skype for Business inherited Lync's architecture — a server-based, IT-managed platform that required on-premises deployment or a hybrid cloud setup. It was complex to administer, brittle in large-scale meetings, and lacked the consumer-grade simplicity that made the Skype brand appealing. The rebrand created confusion: was Skype for Business related to consumer Skype? Could consumer Skype contacts call Skype for Business users? (Not easily.) Was Skype for Business a cloud product or an on-premises product? (Both, uncomfortably.) The dual-brand strategy muddied Microsoft's messaging and diluted both products.
The real damage was temporal. The three years Microsoft spent attempting to make "Skype for Business" work — 2015 through 2017 — were the critical years when
Slack was redefining enterprise communication around persistent chat, channels, and integrations. Slack launched in 2014 and grew to 9 million daily active users by 2017. Its growth was a direct rebuke to the assumption that enterprise communication was primarily about voice and video. The future of work communication was asynchronous, text-first, and organized around projects and teams rather than people and phone numbers. Skype for Business was optimized for the wrong paradigm.
Satya Nadella, who had succeeded Ballmer as Microsoft CEO in February 2014, saw this clearly. Nadella — the quiet engineer from Hyderabad who had spent twenty-two years inside Microsoft, running Bing and then the cloud division, and who understood that Microsoft's future was Azure and Office 365, not Windows licensing — made the call that Ballmer never could. In March 2017, Microsoft launched Teams as a direct competitor to Slack, built natively into Office 365 as a chat-based workspace with integrated video calling, file sharing, and third-party app integrations. By July 2019, Teams had surpassed Slack in daily active users. By April 2020, at the peak of the pandemic, Teams hit 75 million daily active users. By early 2023, it exceeded 300 million monthly active users.
Teams consumed Skype. It didn't replace it — it absorbed its useful functions (video calling, screen sharing, VoIP) and embedded them in a platform that enterprises were already paying for through Office 365 subscriptions. Skype for Business was officially retired on July 31, 2021. Consumer Skype lingered, increasingly ghostly, its monthly active users declining from a peak of 300 million to an estimated 36 million by the time of its final shutdown.
Microsoft Teams brings together everything a team needs — chat, meetings, notes, and attachments — integrated with Office 365.
The Pandemic That Should Have Saved It
COVID-19 was supposed to be Skype's redemption arc. When the world locked down in March 2020 and hundreds of millions of knowledge workers, students, and families suddenly needed video calling software, Skype was the most recognized brand in the category. It had name recognition that competitors would have paid billions for. It had twenty years of trust. It was pre-installed on every Windows computer.
Skype's usage did surge. In March 2020, Skype reported a 70% increase in minutes used, with daily calling minutes reaching 40 million. But the surge was dwarfed — annihilated — by Zoom's explosion. Zoom went from approximately 10 million daily meeting participants in December 2019 to over 300 million by April 2020. Zoom's daily meeting participant count grew by roughly 2,900% in four months. Skype's 70% increase was a rounding error by comparison.
Why Zoom and not Skype? The answer is instructive.
Eric Yuan, Zoom's founder, was a former Cisco WebEx engineer who had left in 2011 specifically because WebEx leadership refused to rebuild the product for the modern era. Yuan understood something that Skype's custodians at Microsoft did not: video calling in 2020 was not a communications utility but a productivity platform, and the product that won would be the one that made the first five seconds frictionless. Zoom's killer feature was the meeting link — a URL that anyone could click to join a video call without downloading software, creating an account, or adding a contact. The join flow was optimized to the point of neurotic perfection. Click. Camera on. You're in.
Skype required a download, an account, a sign-in. In the panicked first weeks of lockdown, when IT departments were scrambling and teachers were trying to teach from kitchen tables, those three additional friction steps were fatal. Zoom captured the moment because Zoom had been designed for the moment — not the moment of a pandemic, specifically, but the moment when video calling would need to scale from power users to everyone.
Microsoft's own answer to the pandemic was Teams, not Skype. Teams was the product that received the engineering investment, the marketing push, the enterprise sales effort. By mid-2020, Microsoft was actively encouraging users to migrate from Skype to Teams. Skype had become, in the cruelest possible inversion, a competitor to Microsoft's own strategic product.
What Was Lost
The financial accounting of Skype's life is surprisingly hard to construct. eBay paid $2.6 billion in 2005 and wrote down $900 million. Silver Lake's consortium paid roughly $2 billion for 65% in 2009 and made approximately $5.5 billion in the Microsoft deal — a spectacular return. Microsoft paid $8.5 billion in 2011.
Did Microsoft get its money's worth? The question requires framing. Microsoft never broke out Skype's revenue separately after the acquisition. What can be said: Skype's calling revenue (SkypeOut, subscriptions) was a declining business by 2014 as mobile carriers reduced international calling rates and apps like WhatsApp offered free calling. The consumer product's user base peaked around 2013–2014 and declined steadily thereafter. The brand had value, but brand value is notoriously difficult to monetize when the product it's attached to is deteriorating.
The case for the acquisition is that Skype's technology and team accelerated Microsoft's development of Teams, which by 2024 was generating billions in revenue as part of the Office 365 bundle and serving as the backbone of enterprise communication for millions of organizations. The real-time communication stack that Skype pioneered — codecs, networking infrastructure, call reliability engineering — was directly repurposed for Teams. In this reading, $8.5 billion was not the price of Skype. It was the price of the capability that became Teams.
The case against is simpler: Microsoft bought a consumer communication platform for $8.5 billion, failed to maintain its consumer relevance, failed to monetize its user base, cannibalized it with its own enterprise product, and shut it down. The technology could have been licensed or developed independently for a fraction of the acquisition cost. The brand, which was the acquisition's most valuable asset, was allowed to decay through years of product neglect.
The deeper loss is harder to quantify. Skype had something in 2005 that almost no technology company in history has achieved: it was the default global communication layer for an entire generation. It connected families across continents. It was the lifeline for immigrants calling home. It was the platform on which long-distance relationships survived, on which grandparents met grandchildren, on which freelancers in Nairobi collaborated with clients in New York. That position — default global communication layer — was worth more than $8.5 billion if properly cultivated. The fact that it was squandered across three corporate parents who each misunderstood its value in different ways is the central tragedy of the Skype story.
A Product in Search of an Owner
The pattern is unmistakable. Three owners. Three theses. Three failures of imagination, each distinct.
eBay saw Skype as a communication layer for e-commerce — a thesis disconnected from how either eBay buyers or Skype users actually behaved. The synergy was theoretical, the integration half-hearted, the result a $900 million write-down and four years of product stagnation during the most critical period in consumer technology history: the birth of the mobile internet.
Silver Lake and its consortium saw Skype as a financial asset — an undervalued consumer internet property that could be cleaned up and flipped. They were correct. They hired Tony Bates as CEO, stabilized operations, grew the user base, and sold to Microsoft at a 200%+ premium in under two years. It was brilliant financial engineering. It was also, by design, short-termist. No private equity consortium with a two-year hold period was going to invest in the multi-year architectural rebuild that Skype needed.
Microsoft saw Skype as a strategic asset — a way to fill the consumer communication gap in its portfolio and block Google, Apple, and Facebook from owning the real-time communication layer. The acquisition achieved the blocking objective. It also inadvertently created the conditions for Teams. But Microsoft never cracked the consumer problem. Under Microsoft's ownership, Skype's consumer product suffered from chronic underinvestment, confused product direction, and the gravitational pull of Microsoft's enterprise DNA. Microsoft is, and always has been, an enterprise company that occasionally pretends to understand consumers. Skype needed an owner who understood consumer products with the intensity that Apple understood hardware or Facebook understood social dynamics.

The Counterfactual
What if Skype had remained independent?
The counterfactual is seductive and probably impossible. An independent Skype in 2005 would have needed to solve the mobile transition with the engineering resources of a startup, not a tech giant. It would have needed to find a revenue model beyond PSTN bridging before that business evaporated. It would have needed to build or acquire a social graph to compete with Facebook's and Apple's distribution advantages. It would have needed to fend off Google, which was willing to lose hundreds of millions on Hangouts to deny competitors the communication layer.
The closest parallel is WhatsApp, which launched in 2009, stayed independent until Facebook acquired it for $19 billion in 2014, and solved the mobile-first communication problem by building the simplest possible messaging app on top of phone numbers. WhatsApp understood that the address book was the social graph. Skype never grasped this — it built a parallel identity system (Skype usernames) that added friction without adding value.
An independent Skype with the right leadership might have pivoted to a WhatsApp-like model — phone-number-based identity, mobile-first architecture, messaging-centric with voice and video as features rather than the core product. This would have required abandoning the peer-to-peer architecture, rebuilding the mobile apps from scratch, and accepting that the desktop-centric power user was no longer the center of the product universe. It would have required, in other words, the willingness to destroy the existing product in order to build the next one. That willingness is the rarest quality in technology leadership, and Skype never had a leader who possessed it at the moment it mattered.
A Green Button Going Dark
The final shutdown was handled with Microsoft's characteristic corporate tidiness. Users were notified months in advance. Migration tools were provided. Chat histories could be exported. Contacts were transferred to Teams. The Skype website displayed a simple message directing visitors to download Teams.
But something else ended too. Skype was, for many people, their first experience of a specific kind of magic — the magic of seeing a face on a screen, in real time, across an ocean, for free. Before Skype, international communication was a luxury, metered by the minute and priced to discourage lingering. After Skype, it was an expectation. That transformation — from scarcity to abundance in human connection — is Skype's permanent contribution to the world, one that no corporate mismanagement or product decline can erase.
In its final months, Skype's monthly active users numbered roughly 36 million — a fraction of its peak, but still 36 million people who, for their own reasons, preferred Skype to every alternative. Immigrants maintaining family ties through decade-old Skype accounts. Small business owners in developing countries who relied on Skype's PSTN calling rates. Elderly users who had learned one video calling application and did not want to learn another.
On the day the servers went dark, somewhere in the world, a grandmother tried to call her grandchild and got a redirect to Microsoft Teams.
