Found this....might be of interest.
Andy Staples has an article about the proposed alliance and it's relation to the 4 million club. It's behind a paywall, so I'll post some highlights.
From 2015-2019 there were 1,593 rated telecasts
198 had 4 million viewers or more.
55 SEC only, 49 Big Ten only, 13 ACC only, 58 interconference/independent games
Only 13 schools had more than 10, Michigan is 3rd with 26, behind Bama (35) OSU (31)
6 SEC schools, 4 Big Ten schools(UM, OSU, PSU, MSU), Clemson, ND, Oklahoma. NOT Texas. only 3 of th5 Red River Shootouts during that span cracked the 4M mark.
The alliance helps create more of those games for the inventory. Also of note, apparently NBC & CBS are interested in the Big Ten, when renegotiation takes place. It's likely they'll have to bid if for no other reason than to have something to compete with ESPN. An alliance would intend to put more games ON CAMPUS while placing a premium on big matchups.
It's a really good article..go check it out.
#1 rated game during that time? 2016 UM vs Ohio
#2 LSU Bama 2019
#4 2018 UM vs OSU
#6 2019 UM vs OSU
#12 2015 UM vs OSU
#14 2017 UM vs OSU
Every game in the top 15 features Alabama or OSU except 1...Texas vs ND 2016
