The latest in music news, music videos, emerging artists and programs devoted to the musical arts: despite what was once claimed, not all of these can be found on MTV. When MTV launched in 1981, it was the country’s source of music videos and music news from around the world, packed conveniently into one television channel. Now, reality shows that do not relate to music in any way are constantly broadcasted, and viewers would be lucky to find any music programs featured at a convenient time. “The Real World,” “Punk’d” and “The Hills” all make millions of dollars and don’t have any musical value.
