 Commercial television in Canada generally used a model similar to the U.S., with networks composed of first-party "owned and operated stations", and third-party affiliates.However, from the 1990s through the 2000s, including CTV Television and its gradual takeover by Baton Broadcasting, and Canwest's acquisition of Western International Communications to expand the Global Television Network and build a secondary television system, Canada's major commercial networks were largely consolidated under their respective conglomerate owners; CTV, Global, Citytv, and most of their respective stations are owned by Bell Media, Corus Entertainment, and Rogers Media respectively.The major English-language networks, including advertising-funded public network CBC Television, have largely used consistent scheduling (besides time zone variations, and adjustments to allow for simultaneous substitution of syndicated programming carried by U.S. broadcast stations available from a nearby market), branding and on-air continuity, with little variation besides local newscasts and public affairs programs (for example, some CTV stations, especially in Western Canada, substitute the network's national morning show "Your Morning" for the local format "CTV Morning Live").
