Coliseum Entertainment

Coliseum Entertainment was an action and older kids' division of Cookie Jar Entertainment. It is primarily known for producing Johnny Test (seasons 1-2) and Dark Oracle, distributing Are You Afraid of the Dark? on DVD in Canada, and co-producing the English dub of Spider Riders. Around 2009, the company was folded into Cookie Jar Entertainment and then it was closed for good when Cookie Jar was acquired by DHX Media.

Company logo
Its logo consists of a white coliseum zooming into the camera and then zooming back out and turning into blue and yellow lines. The music that plays in the background is often the closing theme of the show, but sometimes it used a tribal theme with several Greek-esque yells.
