Overview
CHUM Limited was a Canadian media company headquartered in Toronto and active from the mid-1940s until its corporate dissolution in 2007. Its origins lay in York Broadcasters Limited, a company established by Toronto businessmen to operate CHUM-AM, a radio station that began broadcasting in 1945. The station initially combined news, public affairs, music and sports, but its strategic direction changed after salesman Allan Waters acquired control in 1954. Under Waters, CHUM secured round-the-clock broadcasting, increased its transmission power and developed the operating and financial capabilities that supported a broader media business. The company expanded beyond its original Toronto radio property during the 1960s. It launched CHUM-FM in 1963, acquired interests in Ottawa radio and obtained control of CKVR-TV in Barrie, Ontario. CHUM became a public company in 1967 and subsequently assembled radio assets across Canada. Its CHUM Radio Network syndicated programming nationally and, by the end of its independent existence, the group had interests in or ownership of approximately 33 radio stations. Radio remained an important part of the business, but television became the company’s defining growth platform. CHUM entered Toronto television through CITY-TV, the unconventional UHF station launched by Moses Znaimer in 1972. After CITY encountered financial difficulties, CHUM acquired an initial stake in 1980 and obtained full control in 1981. The station’s distinctive urban, youth-oriented and locally produced style became central to the CHUM television identity. In 1987, CITY-TV and other television operations moved to the CHUM-City Building at 299 Queen Street West in Toronto, a facility that became closely associated with the company and later served as Bell Media’s Toronto headquarters. From the 1980s through the 1990s, CHUM diversified into specialty television and additional conventional stations. Its portfolio included MuchMusic and related channels, Bravo!, Space, Star!, Fashion Television Channel, CP24, SexTV: The Channel and Canadian Learning Television. The company also experimented with station formats. CKVR-TV left the CBC in 1995 and was relaunched with a more contemporary, youth-focused presentation under the New VR identity. CHUM later applied elements of this model to other former network affiliates and, in 2005, organized them under the A-Channel brand. The group also acquired television assets from Baton Broadcasting and Craig Media, integrating several of Craig’s stations into Citytv. CHUM’s final expansion phase included its 2004 purchase of Craig Media for approximately C$265 million, bringing additional conventional stations and digital specialty services into the group. The company’s scale and collection of recognizable channels made it an attractive acquisition target. In July 2006, CHUM agreed to be acquired by Bell Globemedia, later renamed CTVglobemedia. The transaction closed in June 2007 after regulatory review. The Canadian Radio-television and Telecommunications Commission required the purchaser to sell CHUM’s Citytv stations, which were subsequently acquired by Rogers Communications. Most of CHUM’s remaining broadcasting assets moved into CTVglobemedia. CHUM Limited ceased to operate as an independent company after the transaction and was renamed CTV Limited, now part of Bell Media. Bell’s later acquisition of CTVglobemedia restored the former CHUM broadcasting assets to Bell control. The CHUM corporate name disappeared from the successor organization, although Toronto radio stations using the CHUM-AM and CHUM-FM call signs continued to preserve part of the company’s legacy.
History
CHUM Limited began as York Broadcasters Limited, which received authorization in late 1944 to operate a Toronto radio station. CHUM-AM launched on October 28, 1945, initially broadcasting from the Mutual Street Arena with a mixture of information, music, sport and live entertainment. The station was associated with several Toronto businessmen, including station manager Al Leary and company president Jack Part. A decisive transition occurred in 1954, when Allan Waters acquired control. Waters obtained authorization for 24-hour broadcasting and raised the station’s power to 5,000 watts. In 1959, York Broadcasters changed its name to CHUM 1050 Radio Ltd., and the operation moved to Yonge Street. CHUM-FM began broadcasting in 1963. The company entered television through an interest in CKVR-TV in Barrie, ultimately obtaining full control in 1970. CHUM Limited went public in 1967 while continuing to expand its radio holdings. Television became the group’s principal source of creative differentiation after it acquired CITY-TV in Toronto. CITY had been launched in 1972 by Moses Znaimer and became known for unconventional local programming, street-level news and a younger urban audience. CHUM first acquired a minority interest in 1980 and completed its purchase in 1981. The company later moved CITY-TV and related television operations into the CHUM-City Building at 299 Queen Street West. During the 1980s and 1990s, CHUM assembled a broad collection of specialty channels, including MuchMusic, Bravo!, Space, Star!, CP24, Fashion Television Channel, SexTV: The Channel and Canadian Learning Television. It also developed and acquired conventional television stations. CKVR’s 1995 conversion from a CBC affiliate to the independent New VR format became a notable strategic experiment, using contemporary programming and a news style influenced by CITY-TV. CHUM subsequently applied related ideas to other former network affiliates and created the A-Channel identity in 2005. CHUM established a national radio network in 1995 and continued buying media assets. Its 2004 acquisition of Craig Media added five local television stations and three digital specialty services. Some of those stations were integrated into Citytv, while other assets were sold or retained during later regulatory restructuring. After Allan Waters left the board in 2005 and died later that year, CHUM agreed in July 2006 to be acquired by Bell Globemedia, which became CTVglobemedia. Regulatory approval required the sale of Citytv, and Rogers Communications acquired those stations. The remaining CHUM properties transferred to CTVglobemedia on June 22, 2007. CHUM Limited was renamed CTV Limited and ceased to exist as an independent corporate media group. Bell Canada’s acquisition of CTVglobemedia was completed in 2011, creating Bell Media and completing the transition of most former CHUM assets into Bell’s broadcasting division.
