In 1944, the Bureau of Broadcast Measurement (BBM) was formed as a non-profit Canadian radio ratings service. Advertisers and Advertising Agencies controlled two-thirds of the voting power, with broadcasters the other third. The concept was originally born in 1942 by the Canadian Association of Broadcasters (CAB), Association of Canadian Advertisers (ACA) and the Canadian Association of Advertising Agencies (CAAA), now known as the Institute of Communications and Advertising (ICA). A committee was struck, presenting its final report to the CAB at its annual meeting on February 14, 1944. Today, BBM is known as Numeris.
In 1998, "Portuguese Mosaic" became the first community-based programming to air on Camosun College's campus radio, CKMO-FM Victoria.
In 2005, CIVT-DT began testing on UHF channel 33 from Mount Seymour in North Vancouver. It was officially launched on June 21 as "CTV HD West", providing High Definition (HD) television on-air in Vancouver and via digital cable television across much of Western Canada. CIVT-TV first signed on in 1997 on channel 32, and channel 9 on cable. In 2001, CHAN-TV switched to Global and CIVT became the CTV affiliate.
