Global previously maintained a secondary television system similar to CTV 2. CH was originally launched on February 12, 2001 by Canwest Global Communications after acquiring the Western International Communications properties in 2000. The system was launched in September of that year when the large network shuffle in Vancouver occurred, only to provide a secondary schedule parallel to Canwest's larger Global Television Network. It initially focused on airing programs from the U.S. broadcast networks that could not fit on Global's own schedule, in order to avail of simultaneous substitution opportunities. The system became "E!" in fall 2007, as a result of a deal with Comcast to carry programming from that company's U.S.-based E!: Entertainment Television, although it continued to air much the same American network series in primetime and the afternoon.
