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.

Each episode ended with a choreographed song performed by the cast. The cast also had informal chats on subjects such as hospitals, school, family and prejudice, titled Zoomraps. These activities were introduced by such titles as Zoomovie, Zoom Play of the Week, Zoomgame, Zoomdo, Zoomgoody, Zoomphenomenon, etc. 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. The show was revived in 1999 and aired on PBS until 2005. 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. 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. It was originated and produced by WGBH-TV in Boston. 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.
