ABC Classic FM is a classical music radio station available in Australia, and internationally online. It is operated by the Australian Broadcasting Corporation (ABC). It was established in 1976 as "ABC-FM", and later for a short time was known as "ABC Fine Music" (a play on the letters FM), before adopting its current name. It was the ABC's first experiment in FM broadcasting – which had become a necessity in Australia as broadcasters ran out of AM frequencies on which to transmit.
