CHECK it (also known as It's A Fun Thing in Asia) is a new identity for the channel that was introduced on May 29, 2010, along with a new theme and new bumpers. The network's current branding, designed by Brand New School, makes heavy use of the black and white checkerboard which made up the network's first logo, as well as various CMYK color variations and various patterns.
