In 1981, the U.S. video channel MTV launched, airing "Video Killed the Radio Star" by The Buggles and beginning an era of 24-hour-a-day music on television. With this new outlet for material, the music video would, by the mid-1980s, grow to play a central role in popular music marketing. Many important acts of this period, most notably Michael Jackson, Adam and the Ants, Duran Duran and Madonna, owed a great deal of their success to the skillful construction and seductive appeal of their videos.
