Scooby-Doo and Scrappy-Doo (1979 TV series)

The original thirty-minute version of Scooby-Doo and Scrappy-Doo constitutes the fourth incarnation of the Hanna-Barbera Saturday morning cartoon Scooby-Doo. It premiered on September 22, 1979 and ran for one season on ABC as a half-hour program. A total of sixteen episodes were produced. It was the last Hanna-Barbera cartoon series to use the studio's laugh track.

Overview
By 1979, the staff at Hanna-Barbera realized that the Scooby-Doo formula was getting worn out, which gave them reason to parody it in a 1979 prime time special, Scooby Goes Hollywood. In addition, ABC began threatening cancellation for the show, whose ratings were in decline. Therefore, for its 1979 – 1980 season, Scooby-Doo was given a major overhaul, adding the character of Scooby's nephew Scrappy-Doo, voiced by Lennie Weinrib, and changing the name of the show to Scooby-Doo and Scrappy-Doo.

Although still present in these episodes, the characters of Fred, Daphne, and Velma became less essential to the plot, and Shaggy, Scooby and Scrappy were the main focus. Marla Frumkin took over Pat Stevens' role as Velma Dinkley towards the end of the season, beginning with episode 12, "The Ghoul, the Bat, and the Ugly". Velma does not speak in episode 16, "The Ransom of Scooby Chief". Like many animated series created by Hanna-Barbera in the 1970s, the show contained a laugh track created by the studio.
