Zoom (stylized as ZOOM) is a half-hour educational television program, created almost entirely by children, which aired on PBS originally from January 9, 1972, to February 10, 1978, with reruns being shown until September 12, 1980. It was originated and produced by WGBH-TV in Boston. Inspired by educational shows like Sesame Street and The Electric Company, but designed to give the kids who watched it a voice without adults on screen, it was, for the most part, unscripted. Far from seeking to make stars of the child performers, their contracts prohibited them from making any television appearances or doing commercials for three years after they left the show. The show was revived in 1999 and aired on PBS until 2005. Description On the show, a cast of seven kids (ten in Season 4) known as Zoomers presented various activities such as games, plays, poems, recipes, jokes, movies and science experiments, all suggested by viewer contributions. These activities were introduced by such titles as Zoomovie, Zoom Play of the Week, Zoomgame, Zoomdo, Zoomgoody, Zoomphenomenon, etc. The cast also had informal chats on subjects such as hospitals, school, family and prejudice, titled Zoomraps. Each episode ended with a choreographed song performed by the cast. The young Zoomers were only identified by first names, and in the early seasons half the cast were replaced every six months, allowing a set of veteran cast members to help new members become accustomed to the show. The cast was chosen by audition, and the producers made efforts to include children of multiple cultures and backgrounds. The mail-in request became a pop culture reference for its musical exhortation to "Write Zoom, Z-double-O-M, Box 3-5-0, Boston, Mass 0-2-1-3-4: send it to Zoom!". The lines were mostly spoken, but the ZIP Code was sung. In the opening sequence, each cast member performed a brief "signature move," and second season cast member Bernadette's "arm thing" (a helicopter-like series of arm moves) became famous among the show's young audience. By popular demand, Bernadette eventually explained on the show how to perform the move. The program featured its own language, Ubbi-Dubbi, where the syllable "ub" was added before each vowel sound in each syllable of each word ("H-ub-i, fr-ub-iends," etc.). For the first two seasons, a word game called "Fannee Doolee" was featured, in which a series of statements about the titular character were presented to the audience without further explanation (e.g.,
