Toonzai was a Saturday morning cartoon block that aired on The CW Television Network from August 14, 2010 to August 18, 2012. The block was created as a result of a two-year agreement between 4Kids Entertainment and The CW. The original name for the block from 2008 to 2010, The CW4Kids, was retained as a sub-brand through the end of the block’s run in order to fulfill branding obligations per 4Kids Entertainment’s contract to lease The CW’s Saturday morning time slots. The name is a portmanteau of “toon” and the Japanese term banzai, reflecting the majority of anime programming on the block. As of April 12, 2013, the Toonzai website nows redirects to the Vortexx website.
