Two Simpsons fans have broken the Guinness world record for continuous television viewing.

Jeremiah Franco and Carin Shreve, both from California, watched consecutive episodes of The Simpsons for 86 hours and 37 minutes.

100 fans took part in The Simpsons Ultimate Fan Marathon, which was held in Los Angeles at the weekend.

Contestants were allowed to eat and drink throughout the challenge but not fall asleep.

Franco and Shreve each won Simpsons merchandise along with a cash prize of $10,500 (£6,600).

They beat the previous record - set in 2010 by three fans who watched continuous episodes of Kiefer Sutherland series 24 - by 31 minutes.

Twentieth Century Fox, which broadcasts the show in America, hosted the marathon.

The event was attended by the show's creator Matt Groening and several cast members including Nancy Cartwright and Yeardley Smith.

The Simpsons, which was created by Matt Groening, is the longest-running animated comedy show of all time.

The US TV series will broadcast its 500th episode - At Long Last Leave - in the US later this month.
