I can’t believe that it was twenty years ago today that the Cartoon Network first started airing animated programming to kids of all ages on basic cable. The network is stronger than ever with new shows like Adventure Time, Star Wars: The Clone Wars, and the DC Nation as well as the always weird Adult Swim and the newly Resurrection Toonami.

To celebrate their milestone birthday, Cartoon Network has put together this great music video that features just about every character that has ever appeared on the network from the Loony Tunes Characters up to present characters like Ben 10 and Finn and Jake.
