Adult Swim is a Canadian English language discretionary specialty channel owned by Showcase Television, Inc., a subsidiary of Corus Entertainment.

[2] On January 18, 2008, Alliance Atlantis's broadcasting assets were acquired by CW Media, a joint venture between Canwest and Goldman Sachs Capital Partners.

[7][8] By 2011, Action had begun to diverge from its original format, shifting more towards general entertainment and reality shows targeting male audiences.

[15] During Corus Entertainment's 2022 upfronts presentation, the company announced its first two original commissions for the Adult Swim channel; Psi Cops, and Red Ketchup (co-commissioned with Télétoon la nuit).

In order to fulfill Canadian content requirements, the channel also carries reruns of library content (including original series that had been produced for the Teletoon at Night, Télétoon la nuit, and Canadian Adult Swim blocks), and until December 23, 2024 aired made-for-TV films on Monday mornings (a holdover from Action).

By 2011, Action had begun to drift towards airing general entertainment programming targeting a male audience, including acquiring reality shows from the U.S. network TruTV (such as Impractical Jokers).

In 2011, Action would begin airing two original comedy programs, The Drunk and On Drugs Happy Funtime Hour and Kenny Hotz's Triumph of the Will, both of which were cancelled after one season.
