MTV 20: Jams

On August 1, 1981, at 12 midnight, music history was made! Although it didn't seem like it at the time, the launch of MTV, the world's first 24-hour music channel, not only revolutionized the music business, but also transformed film, fashion and television around the world. Not bad for a cable channel that started with a mere eight hours of programming, not advertisers and very few supporters.

On our 20th anniversary, MTV brings you an over-the-top compilation of fifteen groundbreaking Jams music videos that made MTV the cultural touchstone now watched by over 300 million viewers in 139 countries. From "Walk This Way," Run-DMC and Aerosmith's rock-meets-rap, to sexy R&B songstress Erykah Badu's "On & On", you want your MTV
