Let's put a pencil to this. When I was growing up in the 60's, we got to see two games a week for free. Well, it really wasn't free as I lived in Walla Walla and the OTA TV signal wasn't very strong, so my parents bought a cable subscription for $5 a month to get just 3 network stations. We got to see two professional football games each week, the NFL on Sunday mornings the AFL on Sunday afternoons. There was no MNF, SNF, or TNF. It was a 12-game season for both the NFL and the AFL, so that's 24 regular season games we got for free. Each league had 2 playoff games and in 1967, they added the Super Bowl. That's 5 playoff games. Add it all together and that's 29 games we got for free if we ignore the cost of the cable subscription.
There are still at least three and most of the time 4 NFL games on network TV that you can get for free if you have decent OTA reception. We have a 17-game season, including the byes makes it 18 weeks of football. That's well over 60 games, over twice the number of free games we got when I was a kid, and that's just in the regular season before we start counting playoff games and ignoring the $5 cable subscription, about $50 in today's money.
I can piss and moan about a lot of changes that has happened over the course of my 70 laps around the sun, but the entertainment value we're getting out of televised football isn't one of them.
