 NFL executives have called for a three-day weekend in order to allow fans to celebrate the event, and there is thought to be a loss of productivity in the American work force on Monday after the event.The television network carrying the game (either CBS, Fox, or NBC) will usually devote the entire day's programming schedule to the game, with extended pregame shows, NFL Films retrospectives of the previous season, and special versions of the Sunday morning talk shows in the morning and afternoon hours leading into the game.Competing networks, due to the severe loss of viewers to the Super Bowl festivities and a gentlemen's agreement not to compete against the game (most cable and broadcast networks are owned by a limited number of companies, most of which hold NFL rights), generally resort to low-cost counterprogramming measures like the "Puppy Bowl."
