MTV is a Canadian English language cable television specialty channel devoted to talk, lifestyle and documentary programming. MTV is a wholly owned property of CTVglobemedia, with its name licensed from the American channel of the same name, which is owned by MTV Networks, a division of Viacom.The channel launched as talktv in 2000, but was not as widely available prior to its relaunch as MTV in March 2006. Unlike MTV channels in the U.S. and elsewhere, the channel cannot carry music videos and is limited in its ability to carry music programming due to Canadian Radio-television and Telecommunications Commission (CRTC) genre exclusivity restrictions, thus it is just called "MTV" instead of "MTV: Music Television", the full name used in the rest of the world prior to February 2010. MuchMusic, now a sister channel of the Canadian MTV channel, had been launched in 1984 with exclusivity in the mainstream music category.
