I think CBS didn't air "Great Pumpkin" for five years in the 1990s due to the network having discontinued non-educational cartoons at some point in the middle of that decade.
I never knew that, but they still re-aired many of the classic animated Christmas specials that have aired practically every year (A Charlie Brown Christmas, Rudolph, Frosty the Snowman, maybe A Garfield Christmas, and the early ‘90s brought us some new animated Christmas specials like A Wish for Wings That Work).
CBS did premier a handful of new Peanuts specials in the 1990s, but there were also some that were released straight to video (It’s Spring Training was originally planned for a television broadcast before premiering on video much later), as well as NBC airing the Super Bowl special (but I’ve heard that was more because NBC had the rights to the Super Bowl at the time).
Seems television specials in general were rarer in the 1990s, I thought maybe the networks were becoming less interested in specials that don’t represent a holiday or special event or anniversary or honor somebody’s memory. But many franchises I can think of that regularly had specials were being broadcast on CBS. In addition to fewer Peanuts specials being produced, they stopped making new Garfield specials in either 1990 or ‘91 (which I think might have to do with Garfield and Friends being produced, but there were four Garfield specials made after the show premiered), and CBS had been broadcasting new Looney Tunes specials but stopped in 1992 after Bugs Bunny’s Creature Feature had poor ratings, though I recall a few of them were rerun in 1993 (and the ones I know were rebroadcast then weren’t the holiday specials... I recall a 1993 broadcast of Battle of the Music Video Stars and All-American hero, though that might have been around Fourth of July or another patriotic holiday), but the poor ratings led to one unbroadcast special going straight to video and another not going past pre-production (I actually do recall seeing the poor-rated Creature Feature special when it premiered, the only Looney Tunes special I remember seeing when it premiered).
And I feel like the ‘90s (and to an extent the ‘80s) Peanuts specials had become a bit more “kiddie”, so I’m wondering if those specials were more educational than most of the past specials. Why Charlie Brown Why definitely is, but it has been a long time since I last saw many of the specials from the ‘80s and ‘90s.
It’s the Great Pumpkin might not be one of the more educational Peanuts specials, but CBS also stopped airing A Charlie Brown Thanksgiving for about the last 15 years that they had the rights, and that one is about as educational as A Charlie Brown Christmas.
