It really is something how thoroughly MeTV eviscerated RTV...
Cartoon Network is losing product to HBO Max in large part because AT&T is starving their still-tremendously-lucrative cable networks of resources. Nickelodeon has had their heads up their asses for the last 15 years or so and has spent most of the last decade blasting the sort of "hey, remember us?" messaging typical of organizations that are deathly ill (MGM, pre-Eisner Disney, and pre-Turner Hanna-Barbera all come to mind here). The one hit cartoon they've squeaked out since Avatar was quickly embroiled in scandal. I'm so bothered that that asshole turned Dexter's Lab and PPG to shit, AND co-created Trixie Lulamoon.
SpongeBob has literally outlived its creator and from the sound of it the quality of the animation has improved over the last few years, which is good at least.
The Classic Media catalog actually had some neat stuff in it (Rocky and Bullwinkle, Underdog) but they didn't plumb THAT deep apparently.
Truthfully, with the cable bundle severely ailing, I feel like Scripps has an opening to make Qubo competitive, but of course, that takes money, and whatever in-house advantage they'd have isn't there anymore, because they sold it in 2010...that being Peanuts!
