Don't forget 'when' you played, what 'channel', and how much promotion was done for the game. The media controls viewership. That's not to say there aren't contingencies worthy of more promotion. But, let's face it, these numbers are a by product of win/loss and media exposure.
Agree. Putting Stanford on Fox Noon is going to get more eyeballs than Alabama on the SECN at 9pm.
But it isn't 100% timeslot - Bama vs GA is going to get more eyeballs than Iowa vs ISU, even on the same channel at the same time. The opponent matters too. And rankings matter, both for the team and the opponent. There's a lot to tease out there to really get to root cause drivers.
A smarter data analytics mind than mine could determine how much the team matters vs the timeslot, ie the % impact of the teams vs the timeslot, and from there the % differences between the teams. I am sure the TV folks have done it already.
Piqued, I looked at the data I have for 2021. I then looked at the subset of the truly prime games (Fox at noon and afternoon, ABC at noon, afternoon, and evening, and CBS afternoon). There were 76 games. The avg viewership was 4.25M, the median 3.75M. A handful of games (UM-OSU 16M, ALA-AUB 10M, UM-MSU 9M, CLEM-GA 8.9M) really brought the average up a lot.
The standard deviation was 2.4M - so pretty high relative to the average.
Just looking at the top end teams vs the bottom end teams vs the overall averages... I would say, roughly:
best teams are 50-60% above average
worst teams are 25-30% below average
So those best teams are about 2x better than the worst, and that's probably true in every timeslot. 2x is a big difference when game value is exponential per viewer - those top teams games are worth 4x the others.
As far as timeslot impact... from +300% to -75% vs the overall average, or about 10x for the best vs the worst. So a HUGE range, full order of magnitude. But that shows you how important it is to put the best brands and best matchups in the top timeslots to drive that exponential value of viewership. And there are only 6-7 important timeslots per week. Then maybe 5-6 more that are "okay" and then the rest is just filler.
So roughly, the timeslot drives about 70% of viewership, and the teams drive about 30%.
