Joost goes live, gets unlimited invites

Following a limited trial run, Joost today announced that it had officially launched its self-titled Internet TV service. While still in late beta, the peer-to-peer TV network is now said to be in full business and is said to have high-profile ads already lined up to appear this month, including segments from Coca-Cola and HP. Over 150 channels are part of the official launch, ranging from cartoons to documentaries and sports.

Crucially, the company adds, the beta is now far more open: existing testers now have unlimited invites, ensuring that almost anyone can try the service through a friend. A new version of the beta is available for existing users and requires a broadband Internet connection as well as either an Intel-based Mac or a PC running Windows XP.
