"Starting in May 2025, Skype will no longer be available," said a post from Skype support on X, directing users to sign into Microsoft's Teams platform for further use of its services.
Skype was founded in 2003 by Scandinavians Niklas Zennstrom and Janus Friis in Estonia, revolutionizing internet communication by offering free voice calls between computers and affordable rates for calls to landlines and mobile phones.
Over the years, and as internet speeds improved, Skype evolved to include video calls, instant messaging, file sharing and group communication features.
By 2005, Skype had already reached 50 million registered users, demonstrating its rapid global adoption.
Online auction site eBay acquired Skype in 2005 for approximately $2.6 billion, but the expected synergies never panned out, and in 2009, eBay sold a majority stake to a group of investors, who then sold it to Microsoft.
In recent years, especially after the rise of the smartphone, Skype failed to hold onto its place against new rivals such as Meta-owned WhatsApp and Zoom, as well as Microsoft's own Teams.
"We've learned a lot from Skype... as we've evolved Teams over the last seven to eight years," Jeff Teper, president of Microsoft 365 collaborative apps and platforms, told CNBC.
"But we felt like now is the time because we can be simpler for the market, for our customer base, and we can deliver more innovation faster just by being focused on Teams."
Microsoft said that Skype group chats would remain intact in the transition to Teams and that during a 60-day window, messages on Microsoft and Teams will be interoperable so you can message contacts from Teams and those messages will be delivered to friends still using Skype.
In one big change, Microsoft is removing Skype's telephony features, meaning you'll no longer be able to call regular phone numbers, cell phones, or make international calls through the service.
Microsoft told The Verge that these features are no longer as relevant in today's communication landscape where mobile data plans are less expensive.
The name "Skype" derived from "Sky peer-to-peer," the technology that was fundamental to Skype's original architecture.
The peer-to-peer aspect was crucial as it distributed the network demands across users' computers rather than relying solely on centralized servers, which was a key innovation that allowed Skype to scale rapidly during its early years.
