OK trivia buffs, you all know that The Buggles “Video Killed the Radio Star” was the first video aired on MTV, right? To commemorate MTV’s 25th (twenty-five years!) Anniversary you can sacrifice a few more brain cells to memorize #2: Pat Benatar’s “You Better Run.” The entire first hour, including commercials, is available for online viewing at music.mtv.com. You can skip around to segments such as an Atari commercial which features a joystick-wielding dog. VH-1 showed the first 24 hours on Tuesday and will do so again on Saturday.
