Not even Christmas is sacred any longer. From 72 through 88, due to the "longest game ever" between the Chiefs and Dolphins messing up a lot of Christmas dinners, the NFL totally avoided games on Christmas. As an aside, in spite of game going 5-1/2 quarters, the actual run time was just over 3 hours 20 minutes. And the clock stopped on every out of bounds and incomplete pass. Commercials ran when there was a break in the action, they didn't break the action to run commercials. From 1989 to 2019, there were games on Christmas if it fell on Saturday, Sunday, or Monday. Since 2020, Christmas day games are the norm.
