MTV is rolling out MTVU Uber - a user generated content broadband channel. Until recently, the channel was only available on 730 US campuses but now executives have decided to distribute the channel in its entirety over broadband.

The programming focus is on original content, including "the best student-produced" short films, music videos, animation, etc. In a press release, MTVU GM Stephen Friedman says,
"We are handing over an entire channel online to college students and everyone who wants new music. mtvU Uber gives them the power to create and program their own channel, and will remain in perpetual beta mode as they experiment and pioneer the digital future."
