  • Joost development As co-owners of Skype, Friis and Zennström received part of a $2.6 billion cash payment when eBay acquired Skype in 2005, which easily covered the development and marketing cost of their Joost venture. Just a week after launching the service, the founders announced that they had raised additional $45 million. Sequoia Capital, which backed Yahoo, Google and YouTube; Index Ventures, an early investor in Skype; Li Ka-shing, the Hong Kong tycoon; and CBS, the US media group, have all taken “small minority” stakes in the start-up. Viacom is also understood to be among the partners, although the nature of its backing has not been disclosed. [edit] Content distribution As opposed to streaming technology in which all clients get the feed from the server, P2P TV technology differs in the sense that the servers serve only a handful of clients; each of the clients in turn propagate the stream to more downstream clients and so on. This moves the distribution costs from the channel owner to the user. The Joost service will be ad-supported, with advertising analogous to that shown on traditional TV, according to CEO Fredrik de Wahl.[4]
