Recently I've been thinking about the Peanuts specials of the 1990s, mainly how there were so few that decades (with most of them being in the early 1990s) and how some of them were released straight to video (even It's Christmas Time Again, Charlie Brown was released on video a few months before it's CBS broadcast).
I wonder if the early 1990s Peanuts specials had bad enough ratings for CBS to be less interested in new Peanuts specials. It's Spring Training, Charlie Brown was meant to be broadcast on CBS but ended up being released straight to video instead. You're in the Superbowl, Charlie Brown - the last of the regular fully-animated specials to premier on television during Charles Schultz' lifetime - aired on NBC instead (I've seen things that point out that NBC had the rights to broadcast the Superbowl that year, so I don't know if the other networks legally couldn't air anything related to the Super Bowl, or if CBS just didn't want to air this one, or if they felt this special would be better airing on the same channel as the actual Super Bowl). And after that, the remaining fully-animated specials that Schultz made (It Was My Best Birthday Ever and It's the Pied Piper) were released straight to video.
Don't really know if CBS had issues with airing new Peanuts specials, though they continued to air A Charlie Brown Christmas every year until ABC obtained the broadcast rights in 2000 (and ended up getting the rights to air new Peanuts specials). During the 1990s, CBS also had the broadcast rights to It's the Great Pumpkin and A Charlie Brown Thanksgiving, but I've read that CBS went five years without airing The Great Pumpkin in the early 1990s and didn't air Thanksgiving at all in the 1990s (I think CBS didn't broadcast it at all during the networks last 15 years with the broadcast rights).
It seems a number of franchises that were heavily featured in specials throughout the 1980s (and maybe earlier) got less specials in the 1990s, often ending around the early 1990s. Garfield's last special was in either 1991 or 1992, which I thought was more because of Garfield and Friends. CBS was airing new Looney Tunes specials in the late-1980s and early-1990s, I've read at The Bugs Bunny Video Guide that CBS' last Looney Tunes special, Bugs Bunny's Creature Feature, had such bad ratings that they canceled further specials (with Bugs Bunny's Lunar Tunes ending up direct-to-video and another special canceled during pre-production). And there haven't been many Muppet specials since Jim Henson's death (The Muppets Christmas Carol was originally going to be a special, which replaced plans for a Muppet Halloween special... man, we were so close to getting another Muppet special in the early 1990s!).
For the last several years I've noticed that it seems rare for there to be new television specials that don't involve a holiday (especially Christmas) or other current event/anniversary, but could this have occurred in the 1990s? I feel like there were a lot of television specials produced in the 1990s, but it seems like the majority of them were Christmas specials. Were networks suddenly less interested in specials during the 1990s? Of course aside from holiday specials, we got a good number of Sesame Street specials, a few Pete and Pete specials, at least one Eureeka's Castle special that didn't involve a holiday, Dr. Seuss' Daisy-Head Maisy, some Stick Stickly specials, and a network primetime Barney special.
Or maybe, in the case of It's Spring Training, CBS didn't like the special. It is interesting how that one was originally going to be on CBS but not only got released straight-to-video, but its first video release was as part of the Snoopy Double Feature label. Being its first release, I feel it should have been released on its own (put it under the "A Peanuts Special" label), as opposed to with a special that had previously been released on VHS (so fans with a previous copy of the special wouldn't be buying that one again for the new special). I recently read on the Peanuts Animation Guide website that it's first broadcast was on Nickelodeon in 1998, but I recall seeing it on The Disney Channel in 1996 (but I can't just rely on memory).
I am a bit mixed on this one (which I actually haven't seen in years). Seems like it is a bit too kiddie (I feel that's the case with a lot of '80s and '90s Peanuts), I don't really like Lucy's song, I forgot until a few days ago about Franklin's rap song (can't remember how I felt about that), in fact I tend to be mixed about singing when it comes to Peanuts (I like the musical numbers in the first two movies, and the specials based on the two musicals, and I like the song that plays at the end of Someday You'll Find Her, Charlie Brown, but at least as a teenager, I didn't really like It's Flashbeagle, Charlie Brown - though I have a feeling I would like the special better if I watched it now - or Sally's song from Snoopy's Getting Married, Charlie Brown). But on the other hand, it's a rare instance of Charlie Brown's team winning a baseball game, and it seems they get to keep the uniforms they get.
