More About Radio Circulation 730 AM

Telemedia and Radiomutuel Inc. which recently had a merger of their AM facilities in 1994, agree upon a deal which would see Télémédia Communications Inc. acquiring Circulation 730 AM. At that time (late 90s) the radio was increasingly leaning to sports format having broadcasting rights to a number of hockey and football games. Astra Media took control of the assets owned by Télémédia in 2002. CKAC-AM was purchased by Corus Entertainment in Jan 2005. News bulletins were terminated after 80 years of existence. Longtime News and Talk format was removed in favor of an all sports format in April 2007. At the end of year 2010, ownership was again changed when Cogeco came forward to take the ownership of Corus Quebec assets. On Sep 6, 2011, the channel was rebranded as Radio Circulation 730; with the new identity Radio Circulation adopted a completely new format of traffic, road reports and weather conditions.
