The channel launched as Talktv in 2000, but was not as widely available prior to its relaunch in March 2006. Unlike MTV channels in the U.S. and elsewhere, the channel was restricted in its ability to carry music programming until 2015, due to conditions in the channel's licence issued by the Canadian Radio-television and Telecommunications Commission (CRTC). Thus, the channel never used the "Music Television" tagline as its international counterparts did prior to 2010. Instead, MuchMusic had been launched in 1984 as the designated Canadian channel dedicated to mainstream music.
