Toonzai (formerly known as The CW4Kids from May 24, 2008 to August 7, 2010, or stylized as TOONZAi) was an American Saturday morning cartoon children's television block that aired on The CW from May 24, 2008 to August 18, 2012. The block was created as a result of a four-year agreement between 4Kids Entertainment and The CW. The original name for the block from May 24, 2008 to August 7, 2010, The CW4Kids (stylized as THE CW4K!DS), 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.
