The version of the show broadcast on CBS from the late 1970s until it went to ABC was edited, cutting out most of the Trick or Treat/I got a rock sequence. This version was also time-compressed. Some older video releases also edit this sequence and also the scene where Snoopy dances along to Schroeder's World War I-era piano music. Later airings on CBS in the late 1990s would also cut the scene where Lucy pulls the football away when Charlie Brown attempts to kick it. The Paramount video release is unedited.
The original 1966 version had longer opening credits to acknowledge the sponsors. Modern broadcast versions and home video releases have the opening fade away after an owl approaches. One scene that followed was the gang, in their Halloween costumes, being frightened by a ghost dancing on a pumpkin. They run away, and the "ghost" then throws off his white sheet, and we see it was actually Snoopy, who continues dancing.
When ABC assumed the rights of "It's the Great Pumpkin Charlie Brown," an edited version was made to fit in a 21-22 minute time show. The following changes were made:
Since at least 2007, ABC has also aired the unedited version along with an edited version of "You're Not Elected, Charlie Brown," only slightly cutting the transition music after Linus sets up shop in the pumpkin patch.
- The scene where Charlie attempts to kick the football and Lucy pulls it away, even though she claims she has a signed document that prevents her from doing so was edited;
- The sequence of Snoopy dancing to Schroeder's World War I-era piano music was cut
