No, it's gotten worse. There's no denying that stuffty live action shows with stuff writing that rely on being stupid to be funny are the new trend, while we used to have more shows that actually tried to have a sense of humor other than "HWHEDHSEFAHAHA SAUSAGE CHEESE MONKEY IM SO RANDOM!"
I have to say, it's a combination of both. I become physically ill whenever old episodes of Spongebob or the Fairly Odd Parents are on, but Drake & Josh is still funny.
Also, Victorious actually has it's moments
