Bargain Bin Cinema: CTV

The station first signed on the air at 6 p.m. on March 1, 1954. Its signal transmitted from the Baden Tower (a transmitter on Baden Hill), near Baden, just west of Kitchener. The transmitter has become one of the most identifiable landmarks in the area. Originally, like all privately owned television stations in Canada from 1953 to 1959, CKCO was an affiliate of the CBC; it became an affiliate of CTV in 1964. The station increased its transmitter power in the early 1960s to reach London, from which Kitchener then received CBC affiliate programs on CFPL-TV.

CKCO was originally owned by Central Ontario Television, a consortium that included the Famous Players theatre chain (now owned by Cineplex Entertainment) and businessman Carl Arthur Pollock, president of the family-owned television manufacturer Electrohome, although his broadcast holdings – which also included radio stations CFCA-FM and CKKW – were operated by a separate company. At one time, CKCO was owned by CAP Communications, whose name was taken from Pollock's initials; a corporate reorganization in 1970 placed the stations directly under the ownership of Electrohome, which also acquired control of CKCO when Canadian broadcasting laws required domestic ownership of stations, ending the involvement of American-owned Famous Players, which at the time was owned by Paramount Pictures' parent company Gulf + Western (the latter was acquired by the original Viacom). CKCO would become the first station in Canada to provide closed captioning for all of its local newscasts, in 1988.

In the 1990s, Baton Broadcasting had owned competing local stations in southwestern Ontario (CFPL-TV in London, CHWI-TV in Windsor, CKNX-TV in Wingham). A deal between Electrohome and Baton in 1996 resulted in each company owning 50% of these stations, as well as CKCO-TV, among other Canadian stations. The following year, another deal gave Baton control over CKCO-TV, while CHUM Limited took control over the other southwestern Ontario stations (which presently operate as owned-and-operated stations of the CTV Two television system). CTVglobemedia reacquired CFPL, CHWI, and CKNX in 2007 as a result of a takeover of CHUM Limited.

In 1998, Baton changed its name to CTV Inc. after becoming the sole owner of CTV, ending the decades of cooperative ownership of the network. In 2000, BCE purchased CTV Inc. and combined it with NetStar Communications and The Globe and Mail into Bell Globemedia. The company changed its name in 2007 to CTVglobemedia after BCE reduced its ownership interest. In September 2010, BCE re-acquired full ownership of CTV Inc., which changed its name once again to Bell Media in 2011 when the acquisition was finalized.

On October 3, 2005, CKCO ceased identifying by its call letters, adopting the local brand "CTV Southwestern Ontario", with its newscasts rebranding from CKCO News to CTV News. The local brand reflected the fact that, at that time, the station provided some coverage of news in areas southwest of Waterloo Region. While it remains the CTV main-network station for all of Southwestern Ontario, CKCO has since refocused its news-gathering resources exclusively on Waterloo Region and the Guelph area, avoiding direct competition with its sister CTV Two stations in other parts of southwestern Ontario for local news coverage. In early April 2012, presumably to end any confusion about its mandate, the station changed its on-air branding to "CTV Kitchener".
