A Charlie Brown Christmas has been hailed as a staple of the Christmas season for decades since it aired in '65, and launched a legacy for Peanuts as a franchise and a generation of animators. Ironically, it was commissioned by The Coca-Cola Company, and if not for this mega-corporation, this anti-commercialization-of-Christmas special and maybe even all the specials, movies and commercials that would follow would not be possible. Their sponsorship tags would be cut from subsequent broadcasts, although the studio also used this to their benefit to correct the clearest and most fixable animation errors they could notice (while adding a few more in, ironically), the end result having been a disaster in the eyes of Melendez and New York executives in the first place.
The version that has been broadcast and remastered since is the revised version, while the original print would not be screened ever again except during special screenings from an vintage 16mm print. One of these prints was offered to ParamountCartoons, member of the Internet Animation Database forums, who dissected as much as he could from this version, and the print was soon shared as a colour-corrected MKV at the Lost Media Wiki for all to enjoy and examine, and in this video will be compared in split-screen with the changes made in the final cut.
Growing up in Los Angeles in the 70s/80s we visited Disneyland on a regular basis and often after school, before "Annual Passes".
