The TV marathon has become a holiday custom in America, whatever the holiday. For the four (or five) day Thanksgiving weekend, there are plenty, whether you want to binge on Law & Order: SVU episodes, Pawn Stars, Indiana Jones movies, or Thanksgiving episodes of Friends. That’s just the beginning: 13th Annual National Dog Show follows the Macy’s Thanksgiving Parade, as it always does. A TV guide at The Daily Beast lists Christmas movies and specials as well as marathons.
