Boomerang is an American cable television network and streaming service owned by Warner Bros. Entertainment. It originated as a programming block on Cartoon Network introduced in 1992, focusing on classic cartoons from the WB library, and eventually grew into its own separate channel devoted to such content in 2000.

From 2000 to a major rebranding in 2015, the logos used by Boomerang were based on Rat Fink Casual by House Industries. The line “from Cartoon Network” in the secondary logo (shown below) is in Freehand 575, Bitstream’s digitization of Filmotype Jefferson.
