* {{Blooper}}[=/=]OffModel: Several animation errors exist, one of the more obvious being the fact that the words on Lucy's psychiatric help desk change twice in less than a minute. Among others:
** Lucy accidentally calls fear of cats "ailurophasia" instead of "ailurophobia".
** Sally trips over the line "All I want is what I have coming to me. All I want is my fair share."
* ChannelHop: After airing on Creator/{{CBS}} for 36 straight years, the special moved to its present network home of Creator/{{ABC}} in 2001.
* EditedForSyndication: In its original 1965 broadcast, this cartoon clocked in at just over 26 minutes. Nowadays, American TV networks have a ''lot'' more time devoted to commercials than back then. So for most of its subsequent airings, several scenes have been cut short (the first dancing scene) or cut out entirely (much of the beginning). Even in its first VHS release, the scene of the kids throwing snowballs at the can on the fence was cut out. It was restored for its second VHS release and was reinstated in network broadcasts in 1997 (with the Coke can redesigned).
** Coca-Cola was the special's original sponsor, and a brief scene mentioning this was animated for the broadcast. Once their sponsorship ended, that scene had to be excised and was thought lost for decades until a film reel containing it was discovered, digitized, and uploaded onto the internet (rights issues prevent it from being on the DVD cut, though every other scene cut over the decades is restored)
** The recent showings on ABC have taken further cuts, removing such iconic moments as Lucy pestering Schroeder over the proper playing of "Jingle Bells", to even cutting poor Shermy's only line.
* ExecutiveMeddling: CBS executives had [[{{Understatement}} some]] issues with the special as it was originally put together. They objected to:
** The Scripture quotation that Linus recites to explain the meaning of Christmas.
** Using actual children to voice the ''Peanuts'' characters.
** The absence of a {{laugh track}}.
** The Music/VinceGuaraldi jazz score for the program.
** In other words, nearly ''everything'' that makes this program a timeless classic. Fortunately, Charles Schulz and Bill Melendez stuck by their guns and were vindicated the moment it aired.
* MagnumOpusDissonance: '''Nobody''' behind the project thought it was any good when they finished; Lee Mendelson and the rest of the team felt they "ruined Charlie Brown" when they looked at the final cut before it aired.
** It apparently took a while for Charles Schulz himself to realize how iconic this special had become. In the late 1980s he fretted that he hadn't produced his "own ''Film/CitizenKane''" and invested a good deal of time and money on his intended masterpiece, the flop live-action/animated combo ''It's the Girl in the Red Truck, Charlie Brown''. Any fan could've told him he'd already made his ''Citizen Kane'' way back in 1965. (For added irony, Creator/OrsonWelles didn't consider the actual ''Citizen Kane'' to be his masterpiece.)
* NetworkToTheRescue: CBS made some cuts to the special in the '90s because shows made more room for commercials by then (see EditedForSyndication above). When ABC acquired the rights in 2001, they blocked out a full hour for the special so that it could run uncut, commissioning ''Charlie Brown's Christmas Tales'' to fill the extra time. (ABC does air cut half-hour versions some years, but the full version ''will'' be shown at some point during the season).
* WhatCouldHaveBeen: Apparently when the project was started, CBS just wanted this to be a regular goofy ''Peanuts'' short that just happened to take place at Christmas time. They weren't expecting the shots at commercialism and Linus's big speech. It's a good thing the special didn't go this direction, too, because it wouldn't be nearly so memorable otherwise.
** The slam against commercialism and the Bible recitation were only two of what the suits perceived as a laundry list of "issues" with the show. Others were the lack of a laugh track of all things[[note]] (many cartoons in the 1960s had laugh tracks, for example see pretty much the entire Creator/HannaBarbera library prior to 1973)[[/note]], the use of actual children for the voice acting instead of adults, and the Music/VinceGuaraldi jazz score. (The tune [[http://www.youtube.com/watch?v=x6zypc_LhnM "Linus and Lucy"]] became an icon of the franchise, and [[http://en.wikipedia.org/wiki/Vince_Guaraldi#Compositions_for_Charles_Schulz.27s_Peanuts Vince scored 17 other ''Peanuts'' specials and the feature film ''A Boy Named Charlie Brown'']] before his death). Thank goodness Schulz and Melendez stood their ground.
