Before they changed their name to Cookie Jar and then changed again to DHX. I think animation nowadays relies on toilet humor/gaudy colors/storylines and content that is less innocent or "wholesome". This is not saying I watch preschool stuff, but maybe I'm a prude even though you don't really know all that I think. The stuff DiC did even in its last heyday during the 1990's, was clever looking back comparing that to "other" cartoons. Does anyone feel the same change in style?
I would say that, undoubtably, the content has definitely changed over years. You would never have seen a show like Phineas & Ferb on Disney in the 70s or 80s. But this sort of thing could be said of past generations too. Styles and what is viewed as acceptable differ with each passing year.
Not that P & F is foul or anything, just a different flavor of humor that would have probably been seen as too childish or crazy for past generations.
My love of animation has got me in trouble with lots of people I've known over the years. Most folks I've known think of animation as "kids stuff". But my best defense against that has been the credits at the end of every show.
My online friends are aware now of the companies that create/distribute animation, especially on television. DIC, (say Deek - rhymes with geek), is right up there with some of the best in the business. Remember Saban Entertainment, the folks that brought you the Power Rangers and Pokemon? And how about Nelvana, they were behind lots of old favorites of mine, try Eek! the Cat and the Terrible Thunderlizards, lol. Too bad they dropped all plans to make an animated Doctor WHO series back in the 80's - that would've been sooo cool.
Some of the best animated series start with writers. You can't create a great series without a great story. But it makes me wonder what's really behind the poor quality of newer cartoons. Storyboards require time and feedback. The whole process might be too old-fashioned in todays world.
All I know is that stuff that would never make it to production just 15 years ago get green-lighted and but on TV now.
