That’s true but the build up for the NU/ OU game started after OU whipped texass on the 9th of October and ABC built it as the game of the century every week till it kicked off.
Only 2 Pro games played on Thanksgiving just like now, but make no mistake College Football back in those days were more popular than the NFL..
I really don't know how you can say that College Football in that day was more popular than the NFL. On most Saturdays, there was only ONE college football game on TV. At most there would be 2 on special days. New Years day was a football bonanza. 4 games in one day on TV! The money in college football adjusted for inflation was 1/50th of what it is now. At that time, college football was only played on Saturday, except for Bowl Games.
At that time, you could watch 2 NFL games every Sunday and another on Monday night. Almost all of the games were available in the local markets on TV, so the millions of fans in the big cities could watch their team every week. The Superbowl was becoming the biggest event in sports.
College Football's popularity rocketed after the 1984 OU vs. NCAA ruling, allowing essentially for unlimited live games every Saturday, then on other days too.
