CanWest Global Communications was a Canadian media company founded in 1974 by Israel Asper. It became one of the largest media companies in Canada, operating television stations, radio stations, and publishing businesses. The company was known for its ownership of the Global Television Network, which provided a wide range of programming to viewers across the country. In 2010, CanWest faced financial difficulties and filed for bankruptcy protection. The company's assets were eventually sold to Postmedia Network, which focused on its newspaper operations. CanWest's legacy continues to influence the Canadian media landscape, particularly through its contributions to broadcasting and journalism.
