Skype Office, Stockholm, Sweden

• Purchase by eBay
In September 2005, SkypeOut was banned in China. In October of the same year, eBay purchased Skype for $2.6 billion. (In 2011, the Ars Technica estimated the purchase price at $3.1 billion, not $2.6 billion.) In December 2005, videotelephony was introduced.
In April 2006, the number of registered users reached 100 million. In October, Skype 2.0 for Mac was released, the first full release of Skype with video for Macintosh, and in December, Skype announced a new pricing structure, with connection fees for all SkypeOut calls. Skype 3.0 for Windows was released.
In 2006, a now-discontinued feature called "Skypecasting" was introduced. It allowed recordings of Skype voice over IP voice calls and teleconferences to be used as podcasts. Skypecasting remained in beta until it was discontinued. Skypecasts hosted public conference calls for up to 100 people at a time. Unlike ordinary Skype p2p conference calls, Skypecasts supported moderation features suitable for panel discussions, lectures, and town hall forums. Skype operated a directory of public Skypecasts. Skypecasts was discontinued from 1 September 2008.
