A Halloween special, it was the third Peanuts special (and second holiday-themed special, following A Charlie Brown Christmas) to be produced and animated by Bill Melendez. The special features music composed by jazz pianist Vince Guaraldi, whose contributions include the theme song “Linus and Lucy”. It was also the first Peanuts special to use the titular pattern of a short phrase, followed by "Charlie Brown", a pattern which would remain the norm for almost all subsequent Peanuts specials.
Its initial broadcast took place on October 27, 1966, on CBS, preempting My Three Sons. The original sponsors were Coca-Cola, the original sponsor of A Charlie Brown Christmas, and the Dolly Madison brand of baked snack foods, which would go on to be a longtime co-sponsor of the Peanuts specials on CBS. CBS re-aired the special annually through 2000, with ABC picking up the rights beginning in 2001, where it now airs annually during the Halloween season. Since 2006 ABC has usually aired the special twice, once in a truncated format during a half-hour time slot and once in full during an hour-long time slot (filled out with an abridged version of the 1972 special You're Not Elected, Charlie Brown). The special is also aired on Family Channel in Canada since 2018.
Growing up in Los Angeles in the 70s/80s we visited Disneyland on a regular basis and often after school, before "Annual Passes".
