Thanksgiving Day is the time for gathering with family and friends and expressing what you're thankful for, while eating some great food, but it's also a time for TV marathons.

Television networks traditionally air marathons of popular programming during Thanksgiving, for those who don't have plans, those who do have plans and happen to love watching one particular show with friends and family, and anywhere in between.

This year, the networks are airing marathons of classic sitcoms like Friends, Everybody Loves Raymond, Married... with Children and The Simpsons to dramas like Blue Bloods, Criminal Minds, Star Trek and Law & Order to reality shows like Chrisley Knows Best, Pawn Stars, MythBusters and The Real Housewives of Orange County.
