In 1933, Prime Minister R.B. Bennett appointed the three members of the Canadian Radio Broadcasting Commission (CRBC), the successor to the CNR radio network, and the predecessor of the CBC. April 1, 1933, was the official death date of the CNR radio network; imaging on the stations changed from CNR Radio to CRBC.
In 1971, CanCon (Canadian Content) comes to Canadian radio for the first time. With some exceptions based on musical genre, all AM stations in Canada must play 30% Canadian music between 6:00 a.m. and midnight. It would be another few years before FM sees similar requirements.
