Zattoo was founded in US in 2005 by Sugih Jamin, professor for computer science at the University of Michigan, and Beat Knecht, a swiss software product marketing professional and former McKinsey consultant in Silicon Valley.
Zattoo is a Peer-to-Peer IPTV-Service. The main goal is a fast loading, long running Live-Internet-TV for broadband users, broadcaster, content owners and advertisers.
"Advances in broadband, video compression, and multicast streaming technology are rapidly lowering the technical hurdles for Internet and television to merge on a PC. However, there is still the matter of cost. Our streaming network solves that problem by reducing broadcasters' costs by a factor of ten, making it compelling for them to switch to our technology and broaden their service offering," said Sugih Jamin, CTO and co-founder of Zattoo. "Also, Zattoo's proprietary P2P streaming technology ensures a video delivery and smoothness that has until now been impossible to achieve."
Personally, I was impressed by the quality. No interrupt during 30 minutes test and I was surfing throu the web in parallel (Internet-connection: 4000 kb/s download, 400 kb/s upload).
