CBC Music (formerly known as CBC FM, CBC Stereo and CBC Radio 2) is a Canadian FM radio network operated by the Canadian Broadcasting Corporation. It used to concentrate on classical and jazz. In 2007 and 2008, the network transitioned towards a new "adult music" format with a variety of genres, with the classical genre generally restricted to midday hours. In 2009, Radio 2 averaged 2.1 million listeners weekly, and it was the second-largest radio network in Canada.
