You can treat many analyst predictions with a pinch of salt, but at least they're trying to figure out how fast technologies will take off (and who stands to trouser the revenues). Screen Digest has just released a report predicting that by 2011, online TV will be generating £181 million of revenues here. That includes catch-up and on-demand services from the big broadcasters, but also online telly firms like YouTube and Joost (pictured), and download services like Apple's iTunes. It specifically says that the tradiitonal broadcasters will be threatened by the rise of these new online firms, too. If I was ITV, I'd be trying to buy Joost right now.
