The record-keeping group said Dan Jordan, Spencer Larson and Chris Laughlin sat down in front of a set at the TiVo booth of the Consumer Electronics show in Las Vegas earlier this month and reached the record-breaking goal in five days.
The men were allowed 5-minute breaks each hour in accordance with Guinness rules and they were allowed to save the breaks to add up to more time. However, the men said the longest any of them slept at any one time during the attempt was 80 minutes.
Guinness said the men were given regular medical checkups during their attempt and were allowed to eat and drink in front of the TV, but they were not allowed to read or talk on the phone unless they were on a break.
The men split a $5,000 prize at the end of their TV marathon, and they each received a prize package including a television, a TiVo Roamio with product lifetime service, an iPad, a Sonos system, a gamer chair and a year's subscription to Netflix.
"It's been a long week, but it's been fun," Jordan said.
The previous record of just over 86 hours was set by Carin Shreeves and Jeremiah Franco, who sat down for a "The Simpsons" marathon at a 20th Century Fox event in Los Angeles in 2012.
