Boomerang is a cable and satellite television channel owned by Warner Bros.. The Southeast Asian version of Boomerang was launched in September 2005 with a lineup very similar to that of the US version. It started previously as a programming block on Cartoon Network from 2001 to 2005 during weeknights. It has a lot of similarities with the Australian feed, including promos being shared across both feeds.

 

In December 2012, the channel was replaced by Toonami Asia and Cartoonito. However, it was relaunched in Asia on January 1, 2015, with a new look and as part of the Boomerang's global rebranding effort for 2015. The channel replaced the Asian feed of Cartoonito.
