Skype was created by Niklas Zennström, Janus Friis, and four Estonian developers and first released in August 2003. In September 2005, eBay acquired Skype for $2.6 billion.[6] In September 2009,[7] Silver Lake, Andreessen Horowitz, and the Canada Pension Plan Investment Board bought 65% of Skype for $1.9 billion from eBay, valuing the business at $2.92 billion. In May 2011, Microsoft bought Skype for $8.5 billion and used it to replace their Windows Live Messenger. As of 2011, most of the development team and 44% of all the division's employees were in Tallinn and Tartu, Estonia.[8][9][10]
Skype originally featured a hybrid peer-to-peer and client–server system.[11] It became entirely powered by Microsoft-operated supernodes in May 2012;[12] in 2017, it changed from a peer-to-peer service to a centralized Azure-based service.
As of March 2020, Skype was used by 100 million people at least once a month and by 40 million people each day.[13] During the COVID-19 pandemic, Skype lost a large part of its market share to Zoom.[14]
As of February 2023, Skype was used by 36 million people each day.[15]
