Old vs New?

So I was watching Challenge on FoodNetwork (there is a point why a bring up food) and it showed clips of Charlie Brown's Thanksgiving and it got me thinking of how old cartoons use to be.  I still have this movie somewhere in my house and I remember watching this with my mother and brother around Thanksgiving obviously.  Then I flipped the channel to Cartoon Network and Annoying Orange was on.  Oh my god I frigin hate those guys.  It is so stupid!!! I mean I know the animation in cartoons has advanced but my god is this the best people can come up with these days?  Really?  What happen to the old cartoons like Charile Brown, Cat Dog, Hey Arnold, Doug, As Told By Ginger etc...I use to wake up every Saturday to watch my legit "Saturday morning cartoons".  Now besides Adult Swim (I think Toonami is working with them because they are doing the cartoons on Sunday morning)which thankfully still air good anime shows  I really don't watch that much cartoons anymore.  Most of them seem pointless...well except a few like Phineas and Ferb and SpongeBob...but I mean that square yellow dude has been around forever.  So what happened to all the cartoons that a lot of us growing up with?  Is there a reason for the I.Q. of most t.v. shows to drop in order to increase audience size?  Is it because this stupid mindless-for lack of a better word - crap, is what we as kids/adults are so use to seeing that it has become the new norm for cartoons; the dumber the better?  Heck I would even settle for really old shows like I love Lucy or I Dream of Genie. I watch that on the Hallmark channel in P.A. and it is really good!  So which do you choose?  Old classics or new fresh cartoons.
