MTV (formerly an initialism of Music Television) is an American basic cable and satellite television channel which is a part of the "Viacom Music and Entertainment Group" unit of the Viacom Media Networks division of Viacom, of which it is a subsidiary. The channel itself is headquartered in New York City. Launched on August 1, 1981, the original purpose of the channel was to play music videos guided by television personalities known as "video jockeys," or VJs. The network's current target audience is teenagers and young adults, with programming consisting mainly of original reality, comedy and drama programming and some off-network syndicated programs and films, along with limited music video programming in off-peak time periods. In its early years, MTV's main target demographic were young adults, but today, MTV's programming is primarily targeted at teenagers, high school students and college-aged students.

AMV is a proprietary video file format, produced for MP4 players, as well as S1 MP3 players with video playback. There are now two different MTV formats: the older one for the Actions chip, and a newer one for ALi’s M5661 chip. This format for ALi one was ALIAVI.

MTV Plus was a digital entertainment television channel available in Greece and an Italian version also aired until it was replaced with MTV Music on March 1, 2011.
