Scooby-Doo
The first episode of "Scooby-Doo, Where Are You!" "What a Night for a Knight" debuted on the CBS network Saturday, September 13, 1969. The original voice cast featured veteran voice actor Don Messick as Scooby-Doo, radio DJ Casey Kasem (later host of radio's syndicated "American Top 40") as Shaggy, actor Frank Welker (later a veteran voice actor in his own right) as Fred, actress Nicole Jaffe as Velma, and musician Indira Stefanianna Christopherson as Daphne. Scooby's speech patterns closely resembled an earlier cartoon dog, Astro from "The Jetsons" (1962–63), also voiced by Messick. Seventeen episodes of "Scooby-Doo Where are You!" were produced in 1969–70. The series theme song was written by David Mook and Ben Raleigh, and performed by Larry Marks.
The New Scooby-Doo Movies
In 1994, "The New Scooby-Doo Movies" began appearing on three Turner Broadcasting networks: TNT, Cartoon Network and Boomerang. Like many animated series created by Hanna-Barbera in the 1970s, the show contained a laugh track created by the studio. The first season of the series was animated at Hanna-Barbera's main studio in Los Angeles, while the second season was animated at their newly formed studio in Australia.
Upon attempting to release a complete series set of the entire "24-episode" show on DVD in 2005, Warner Home Video was unable to negotiate agreements with several of the episodes' guest stars to have those episodes included in the DVD set. As a result, the DVD was released under the title "The Best of the New Scooby-Doo Movies", and features only 15 episodes culled from both seasons. The opening titles on this release were edited to remove the images of The Addams Family, Batman & Robin, The Harlem Globetrotters, The Three Stooges, and Laurel & Hardy. It is still unknown if Warner Home Video will ever release a complete set or a second compilation for the remaining episodes.
