Production
Yo Yogi! featured episodes, or parts of episodes, in 3D, with Kellogg's Rice Krispies offering 3D glasses. Generally, the 3D scenes were chase scenes of the variety made famous by Hanna-Barbera in the Scooby-Doo series. At the beginning of these 3D sequences, Yogi would spin his hat atop his head, as a cue to viewers to don their 3D glasses. On March 6, 1992, in response to the success of its Saturday morning live-action teen sitcomSaved by the Bell, NBC announced that it had cancelled its entire Saturday morning block of cartoons and would be replacing the cartoons with a new block of live-action shows targeting teenagers in addition to a Saturday edition of The Today Show. Yo Yogi! last aired in syndication as part of The Funtastic World of Hanna-Barbera. Modern voice actors played the voices of certain characters not only because some of them are teenagers, but due to the deaths of Daws Butler, Mel Blanc, and Paul Frees before this series began.
In the early '90s, a VHS release of the show came with 3D glasses. As of 2018, there are no plans for a complete series set release from either Warner Home Video or Warner Archive. However, it is available on iTunes as part of the Hanna-Barbera Diamond Collection.
