Boomerang is a 24-hour American cable television channel owned by Turner Broadcasting System, a division of Time Warner. Boomerang specializes in reruns of animated programming from Time Warner's extensive archives, including pre-1986 MGM, Hanna-Barbera, Cartoon Network, Warner Bros. Animation, and DePatie-Freleng Enterprises programs, stretching from cartoon shorts of the 1930s and 1940s (almost always in color) to repeats of shows still in production on Cartoon Network. The channel debuted on April 1, 2000.

Much of the programming that makes up the core of Boomerang's current lineup was originally part of TBS's Disaster Area, a block of children's programming that aired throughout 1997 to 1999.

Boomerang was originally a programming block on Cartoon Network started in December 1992. It was aimed towards the generation of baby boomers, and was similar to a similar block on the Disney Channel, Vault Disney. It originally aired for four hours every weekend, but the block's start time jumped frequently. The Saturday block moved to Saturday afternoons, then back to the early morning, and the Sunday block moved to Sunday evenings. Eventually, Boomerang was shortened by an hour, making the total airing time 3 hours each weekend instead of the original four hours. In 2000, Boomerang received both a new look and the cable spin-off channel that launched on April 1, 2000. By then, the block followed a unique programming format—every week, cartoons produced during a certain year (and cartoons produced during years prior to that year) would be showcased. For example, if Boomerang was showcasing the year 1969, the viewer would more than likely see an episode of Scooby-Doo, Where Are You! or Dastardly and Muttley in Their Flying Machines.
