open was also both the oldest and the more successful according to recent BBM ratings, this was not the case everywhere—CJTR in Trois-Rivières had recently surpassed CHLN in ratings for the first time in many years, and CKCH in Gatineau (opened in 1933) had much more of a history than CJRC, which opened only in 1968. The Radiomédia network, along with CKAC in Montreal and CHRC in Quebec City, were now owned in equal shares by Telemedia and Radiomutuel. Telemedia retained full ownership of CHLT in Sherbrooke and CHLN in Trois-Rivières, while Radiomutuel retained full ownership of CJRC in Gatineau and CKRS in Saguenay. Both companies continued to compete against each other on the FM dial, with Telemedia still owning the RockDétente network and Radiomutuel owning the Énergie network, this while both FM networks were now getting their news services from the Radiomédia newsrooms. Change to Corus Québec After Astral Media (successor to Radiomutuel) bought all Telemedia Quebec radio properties in 2001, it was forced by the Competition Bureau to sell their AM stations due to concentration of ownership concerns. After two failed attempts (see article on CKAC for more details), a deal with Corus Entertainment was finally approved in early 2005 and took effect in May of that year. Corus Entertainment, which already owned all-news station CINF (Info 690) in Montreal, promptly renamed Radiomédia as Corus Québec, and simultaneously dismantled the local CKAC newsroom, even though that newsroom was much more respected by listeners than the one from Info 690. News bulletins on the Corus Québec network were now provided by CorusNouvelles, which consists of the old Radiomédia team outside of Montreal combined with the Info 690 team in Montreal. Production of CorusNouvelles would shift to CHMP-FM in January 2010, following the closure of CINF and its English-language sister station, CINW 940 AM. Sale to Cogeco On April 30, 2010, it was announced that all Corus Québec stations, with the exception of CKRS, will be sold to Cogeco for $80 million, pending CRTC approval. Corus's reason for the sale is that their Quebec radio stations are less profitable than their stations in other parts of Canada. However, Cogeco must either apply with the CRTC for an exemption from the common ownership policy, or sell off some of these (or their own) stations as they will be over the maximum allowable number of stations in Montreal, Quebec City, and Sherbrooke.
