HBO (which stands for Home Box Office) is a premium cable television channel that specializes in showing movies, as well as original films and series.
Among the Henson productions that originally aired on HBO are Emmet Otter's Jug-Band Christmas (1977), Fraggle Rock, (1983-1987), The Tale of the Bunny Picnic (1986), and The Ghost of Faffner Hall (1989). Additionally, the Muppets appeared in the HBO special The Vent Event (1978).
In 1983, HBO held a Fraggle Rock Sweepstakes contest. The grand prize was a trip for a family of four to Fraggle Rock at Toronto's CBC Studios or New York City for the Macy's Thanksgiving Day Parade and a tour of The Muppet Workshop. Other prizes were a Fraggle Fun Pack which included a Fraggle Rock record and poster, and a year's subscription to HBO. A promo was filmed for this contest featuring Doc and Sprocket reading about the contest in a newspaper. Doc encouraged Sprocket to enter the contest so that they can figure out what a Fraggle is. Gobo Fraggle makes a silent appearance at the end as he overheard Doc's conversation. The contest ended on May 31, 1983.
In 1997, HBO aired The StoryTeller, both re-runs and "The Three Ravens," which had not aired in America, and The StoryTeller: Greek Myths, making its belated US debut. In November 2006, two performances of Puppet Up! were filmed as part of HBO and AEG LIVE's "The Comedy Festival" at Caesar's Palace in Las Vegas.
On August 13, 2015, it was announced that Sesame Workshop entered a partnership with the channel for new episodes of Sesame Street to premiere on HBO before airing on PBS, starting with season 46. HBO Latino will simulcast the series in Spanish and episodes from the show's extensive library are made availible on the HBO Kids section of the HBO GO/Now services.
