The New Scooby-Doo Movies is an American animated mystery comedy television series produced by Hanna-Barbera for CBS. It is the second animated television series in the studio's Scooby-Doo franchise, and follows the first incarnation, Scooby-Doo, Where Are You!. It premiered on September 9, 1972 and ran for two seasons on CBS as the only hour-long Scooby-Doo series. Twenty-four episodes were produced, sixteen for the 1972–73 season and eight more for the 1973–74 season.
Aside from doubling the length of each episode, The New Scooby-Doo Movies differed from its predecessor in the addition of a rotating special guest star slot; each episode featured real world celebrities or well known animated characters joining the Mystery, Inc. gang in solving mysteries. Some episodes, in particular the episodes guest-starring the characters from The Addams Family, Batman, and Jeannie, deviated from the established Scooby-Doo format of presenting criminals masquerading as supernatural beings by introducing real ghosts, witches, monsters, and other such characters into the plots.
The series first aired on Boomerang from the channel's launch on April 1, 2000 until January 2, 2015. After it was originally removed from Boomerang's line-up, it returned to Boomerang's schedule on April 27, 2015, but it was removed again on January 29, 2016. The series returned to Boomerang's schedule once again on January 1, 2018, and left the schedule again on July 29, 2018.
