 In order to avoid confusion and trademark issues with Canadian broadcast network CTV, now owned by BCE Inc subsidiary Bell Media, the name of the channel was subsequently changed to Comedy Central on June 1, 1991, with the name "Comedy Partners, Inc." appearing on the end credits of all shows produced by the new channel.The original Viacom which operated Ha!, (not the current version which owns Comedy Central) bought out the Time Warner (which operated The Comedy Channel and belonged to HBO) half of the network in 2003.Since the purchase, the name "Comedy Partners, Inc." remained on the closing credits on most Comedy Central shows.
