The Simpsons celebrate their 20th anniversary this week on Thursday, and CNN Entertainment published this chart "The Simpsons Comedy Tree" on Monday.  A combination Nightingale Rose Graph (also called a polar area diagram), family tree and timeline, this simple chart connects the influences that impacted Matt Groening and the creators of the Simpsons as well as the shows that came after.

"The Simpsons" stands on the comedic shoulders of many that came before -- and has influenced countless works that have arrived since. Here are just a few of the roots of the "Simpsons" comedy tree and the branches of those it gave life to. (The following, illustrated by the doughnut at the top of the story, is by no means complete, and each member has its own, sometimes overlapping influences.) 

Thanks to Tony Hendra's "Going Too Far" for inspiration and cartoonist Art Spiegelman for having his fingerprints all over the place.

The article also includes descriptions of the actual influence for each of these shows.

Thanks for the link Matt!
