Who wants my MTV?

MTV made its debut 25 years ago last week. The channel that began with music videos went on to give us reality shows like "The Real World," "Beavis and Butthead" and "Laguna Beach: The Real OC." Today, on the heels of yesterday's announcement that Google will distribute MTV programming starting later this month, we debate the significance of the channel. Has its dominance been eroded or does it remain a force in youth culture? Also on the show: Ollabelle, a band that mixes elements of traditional country, gospel and blues music, and which comes out of the vibrant roots scene of the East Village. Today they perform music from their second album, "Riverside Battle Songs."
