London pioneered in the establishment of cable television in Canada, being either the first or second city in Canada with cable service, when Ed Jarmain and others wired the first 15 homes, and had to purchase TV sets for 14 of them. London's first cable system, established in 1952, broadcast American signals that crossed the border, including WICU from Erie, Pennsylvania. Shortly afterward, another cable operator, named Community Television was also established serving southwestern London and a "gentleman's agreement" set a boundary, convoluted in the old London South (Wortley Road) area; Community Television was later purchased by Maclean-Hunter, and Maclean Hunter was ultimately purchased by Rogers Cablesystems. London Cable TV later merged with Canadian Cablesystems, a cable operator owned by the Famous Players Theatre chain, with Jarmain remaining as chief executive. Canadian Cablesystems was acquired by Rogers in 1978, and Rogers purchased Maclean Hunter in 1993. Rogers TV Cable 13, brings around 60 of the 76 home and away games of the London Knights of the Ontario Hockey League. In the 2009 OHL Playoffs Rogers TV carried all home and away games in the London Knights schedule. This was the first time games from the Tulio Arena in Erie, PA and The Dow Event Centre in Saginaw, MI were broadcast on Canadian television. Rogers TV also has exclusive coverage of the Western Mustangs.
London had the second private local television station in Canada, CFPL (on-air November 28, 1953), and CFPL was the first Canadian local channel to broadcast in colour (1966). As part of CHUM Limited's NewNet system was branded as The New PL. In August 2005, CFPL was re-branded as A-Channel. In August 2008, A-Channel was re-branded to A, effectively re-branding the CFPL station once more and in August 31, 2011, A was re-branded as CTV Two. Several other stations from neighbouring cities have established retransmitters or are otherwise available in London, as follows:
