You ask the average American or European for that matter, what is the longest animated TV show and they would probably say, “The Simpsons,” and they would be wrong. Even at one point, Guinness declared Scooby Doo with this honor. http://www.dexigner.com/news/2940 which was even more absurd.
I am happy to say that this long time injustice has been rectified.
As of this writing, the Simpsons has over 530 episodes…. In 2004, Scooby Doo hit 350. Not sure what the current number is yet. The true champion is none other than Sazae-san, which clocks in at 2,250 episodes. Yes, that’s right… a FOUR digit number. Guinness has finally rectified this travesty. http://www.animenewsnetwork.com/news/2013-09-05/guinness-certifies-sazae-san-as-longest-running-animated-show
