How Skype Worked — And Why It Failed

How did Skype change internet communication, and why did Microsoft shut it down? Discover the technology behind Skype, its revolutionary peer-to-peer (P2P) network, and the rise and fall of one of the most iconic communication platforms in internet history. Launched in 2003, Skype transformed the way people communicated online. Using peer-to-peer technology, it made free internet calls possible for millions of people around the world and became one of the biggest names in VoIP and video calling. But everything changed when Microsoft acquired Skype for $8.5 billion in 2011. In this video, we explore how Skype worked, the peer-to-peer architecture behind its success, Microsoft's transition to cloud-based infrastructure, and the business decisions that changed the platform forever. We also examine how Zoom and Microsoft Teams reshaped the video conferencing industry during the COVID-19 pandemic, ultimately contributing to Skype's decline and shutdown on May 5, 2025. From groundbreaking internet technology to one of the biggest stories in software history, this is the rise and fall of Skype. *CHAPTERS* 00:00 The Rise of Skype: How It Changed Internet Calling 00:49 How Skype Worked: Peer-to-Peer (P2P) Technology 02:36 Why Skype Failed: Microsoft, Zoom & Teams Chapter timestamps will be updated. #Skype #Microsoft #Technology
