The lines between the internet and TV - and between content users and content producers - continue to blur as TV networks and advertisers attempt to find ways to integrate user-generated content into their offerings.

TV networks are attempting to replicate the YouTube model by allowing users to submit video clips and vote on their favorites, Business Week writes. The challenge for TV will be to match the variety of the choices available online, where users can pick and choose from millions of clips.

What advertisers and TV networks are apparently hoping is that adding user-generated content to their offerings will help make their ads and shows more relevant with viewers who are already enjoying such content online.

"It has huge long-term implications," says Joel Hyatt, co-creator of Current TV, a network that lets viewers submit video clips, which account for a third of the network's programming. "This is not a genie that's going back in the bottle."
