All of the former Alliance Atlantis specialty networks, except for the now-defunct BBC Kids, are now owned by Corus Entertainment. The films division was later acquired by Entertainment One group and folded into eOne on January 9, 2013.

The Alliance name currently survives under the Alliance Cinemas banner now owned by Cineplex Entertainment.
