When the Simpsons made their first appearance, in 1989, they were only a pack
of demented yellow cartoon characters, prone to violence and beer chugging.
These two-minute shorts appeared during "The Tracey Ullman
Show." Today the show incorporates ... morehundreds of characters, celebrity cameos
and has introduced "D'oh!" to the English language. Truly, "The Simpsons" is the
reigning champion of prime-time cartoons.
