CHUM Limited

CHUM Limited was a media company based in Toronto, Ontario, Canada from 1945 to 2007. Immediately prior to its acquisition, it held full or joint control of two Canadian television systems — Citytv and A-Channel (formerly NewNet, now CTV Two) — comprising 11 local stations, and one CBC Television (Canadian Broadcasting Corporation) affiliate, one provincial educational channel, and 20 branded specialty television channels, most notably MuchMusic and its various spinoffs. In addition, CHUM controlled 33 radio stations across Canada. At various points in its history, CHUM owned other radio stations and ATV/Atlantic Satellite Network in Atlantic Canada.

CHUM was taken over by Bell Globemedia (now Bell Media), owner of the CTV Television Network in July 2006. Regulatory approval was made conditional on the sale of CHUM's five Citytv stations to Rogers Communications. CTVglobemedia took control of CHUM's other assets effective June 22, 2007. The company itself has since been renamed CTV Limited (now CTV Inc.) and continues operation as a subsidiary of Bell Media. Its radio broadcasting division, CHUM Radio has since became Bell Media Radio after Bell Canada took control of CTV's assets, thus becoming Bell Media. Its Toronto radio stations TSN RADIO 1050 and 104.5 CHUM-FM continues use "CHUM" as their station's call sign. However, CHUM no longer operates as a broadcasting company separate from its new parent.

With the sale of CTVglobemedia to Bell Canada as announced in September 2010 (pending CRTC and Competition Bureau approval), Bell would (if approved) take control of most of CHUM's former assets for the first time. And CTVglobemedia became known as Bell Media in April 1, 2011, after the deal to purchase the stations was finalized.
