At the Convergence 2.0 conference in New York on Monday, an NBC executive said that the network plans to market its new fall lineup of shows by broadcasting user-created "mashups" of NBC video clips as on-air promos. Gillian Lusins, vice president for intellectual property at NBC Universal, said the company plans to provide an online video-editing tool that lets users modify and remix video clips from its shows to create their own in-house promotional spots. eWeek's Steve Bryant speculates that NBC will use Flash, since the popular Adobe Web-video format is harder to copy (and therefore pirate) than other formats.

In a related development, NBC and web video outfit YouTube announced a partnership today where NBC will provide official promotional clips to YouTube, and YouTube would host a make-your-own promo contest for NBC's "The Office." While that seems like a halfway step to Lusins' vision of hosting video tools on NBC's own websites, "The Office" contest, as well as NBC's plans to broadcast user-generated mashups, should delight Todd Copilevitz of the Advertising Ourselves to Death blog, since he asked in May when NBC would start broadcasting user-generated content over the air, not just on its websites.

Do you think many people will bother putting together videos for a broadcast network?
