2010 Muchmusic Vedio Music Awards

MuchMusic was launched in part to capitalize on the success of MTV, the American cable music channel that had premiered a few years earlier. Although never an affiliate, Much over the years would often broadcast MTV-produced programming such as awards shows, concerts, reality TV series and more. MTV itself was not permitted in Canada because of Canadian Radio-television and Telecommunications Commission (CRTC) restrictions on format protection. However, no such restrictions existed in the United States, where CHUM attempted to compete with MTV through MuchUSA (now the unaffiliated Fuse).

MuchMusic was licensed on April 2, 1984 by the Canadian Radio-television and Telecommunications Commission (CRTC) to CHUM Limited. Shortly thereafter, MuchMusic was launched on August 31, 1984 as one of the first Canadian cable specialty channels on the air. It was headed by John Martin and Moses Znaimer, the channel's founders. On June 22, 2007, CTVglobemedia gained control of MuchMusic as a result of a takeover of CHUM Limited.

The first video played on MuchMusic was "an early music-to-film synchronization short from the 1920s which featured Eubie Blake performing Snappy Songs." The first video made specifically for television air play was Rush's "The Enemy Within".
