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.
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" as she, Fred, and Daphne weren't seen much in that episode. Like many animated series created by Hanna-Barbera in the 1970s, the show contained a laugh track created by the studio.
Scooby-Doo and Scrappy-Doo can refer to several versions of Hanna-Barbera's Scooby-Doo Saturday morning cartoon series:
The Scooby-Doo and Scrappy-Doo shorts represents the fifth incarnation of the Hanna-Barbera Saturday morning cartoon Scooby-Doo series. A total of 33 half-hour episodes, each of which included three 7-minute shorts, were produced over three seasons, from 1980 to 1982 on ABC. Thirteen episodes were produced for the 1980–81 season, and seven more for the 1981-82 as segments of The Richie Rich/Scooby-Doo Show. The remaining thirteen episodes were produced as segments of The Scooby & Scrappy-Doo/Puppy Hour for the 1982-83 season. Out of the 99 shorts that were produced, 86 of them feature Scooby-Doo, his nephew Scrappy-Doo and Shaggy without the rest of the Mystery Inc gang, and the other 13 were back-up segments that only featured Scrappy-Doo and Yabba-Doo.
