The Simpsons was created by Matt Groening, 60, and originally ran as shorts on The Tracey Ullman Show in 1987.

After three seasons, the shorts were developed into a half-hour prime time show that debuted on December 17, 1989 as a Christmas special.

The Simpsons have won 28 Primetime Emmy Awards, 30 Annie Awards and a Peabody Award.

Famous voices: Yeardley Smith, left, who voices Lisa is seen in June in Los Angeles and Nancy Cartwright who voices Bart is shown in February at her alma mater UCLA at the 41st annual Annie Awards

The parents: Julie Kavner who voices Marge is shown in September 2011 in New York City and Dan Castellaneta who voices Homer is shown in December 2009 in Los Angeles

Homer's catchphrase 'D'oh!' has entered the American lexicon while the show has become the longest-running US sitcom, the longest running American animated program and the longest-running US scripted primetime TV series.

The show's other notable catchphrases include Marge's questionable 'Hmmmmmm', neighbor Ned Flander's greeting 'Hi-Diddily Ho!' and schoolyard tyrant Nelson's 'Haw Haw!'

The Simpsons Movie was released in July 2007 and the feature-length film grossed more than $527 million.

Groening also created the animated sci-fi sitcom Futurama that ran on Fox for seven seasons.

The cartoonist also published the weekly comic strip Life In Hell that ran for 32 years in the now defunct Los Angeles Reader and later in the LA Weekly until Groening pulled it in June 2012.

Life In Hell with its odd, angst-filled anthropomorphic rabbits reached the attention of Hollywood producer James L. Brooks who contacted Groening in 1985 to provide the animated shorts for The Tracey Ullman Show.
