On "TeenNick Top 10" viewers get their say in what the week's top 10 music videos are in this countdown show hosted by Nick Cannon. But it's not just about what's popular in music, videos and culture for the week. Cannon also chats with celebrity guests, gives his thoughts on up-and-coming artists, and talks about events that are happening in cities across the world. Because Cannon is busy with a number of different gigs, he doesn't host the countdown from one location every week. He can be found hosting the show in the studio, on set or in his office in Times Square.
