Turkish radio stations often broadcast popular music. Each music station has a format, or a category of songs to be played; these are generally similar to but not the same as ordinary generic classification. With the introduction of commercial radio and television in the early 1990s ending the monopoly of the Turkish Radio and Television Corporation (TRT), a multitude of radio and TV stations were opened by newspaper media moguls. These media chains sponsor award ceremonies such as the "Kral TV" awards for music, but most accredited music awards are based on sales given out by industry societies such as MÜ-YAP and the Magazine Journalists Society (MJS).
