Hanna-Barbera's 50th: A Yabba Dabba Doo Celebration

Hanna-Barbera's 50th: A Yabba Dabba Doo Celebration, titled onscreen as A Yabba Dabba Doo Celebration: 50 Years of Hanna-Barbera, is a 1989 live-action/animated television special. Originally airing on TNT, the special featured hosts Tony Danza and Annie Potts celebrating 50 years of William Hanna and Joseph Barbera's partnership in animation. This is the first animated project to be presented in Dolby Surround sound system.
Covered are Hanna and Barbera's years working for the Metro-Goldwyn-Mayer cartoon studio, and then the history of Hanna-Barbera Productions Inc., which was set up in 1957. Featured are many clips from the studio's classic works, with particular focus going to Tom and Jerry, The Huckleberry Hound Show, The Quick Draw McGraw Show, The Yogi Bear Show, The Jetsons, and The Flintstones. The special also included new animated/live-action material, including several musical performances by the Hanna-Barbera characters, and a behind-the-scenes look at the then-upcoming Jetsons: The Movie.
As a running gag throughout the special, Fred Flintstone keeps pestering the hosts to ask when they are going to get to his show's montage. Also, each act opens with celebrities giving anniversary greetings and attempting to sing the Flintstones theme song. Some do a better job than others. 
The special was dedicated to the memory of Daws Butler, who died during this collaborative production. It was also the last television and film project for Mel Blanc, who died seven days before the special's telecast. This marked the final time Mel Blanc voiced Barney Rubble.
