Oh yeah, one more thing: What matters is EYEBALLS (either cable, TV or streaming/digital).
With the addition of UCLA and USC, and to a lesser degree U Wash, the Big Ten now completely controls the following Media/DMA markets (with their percentage of the US market):
#1 - New York - 6.5%
#2 - Los Angeles - 4.8%
#3 - Chicago - 3.0%
#4 - Philadelphia - 2.6% (true, in hoops Villanova has some sway here, but in football it is all Penn St - even RU has presence)
#7 - DC/Hagerstown - 2.2%
#13 - Detroit - 1.6%
#14 - Seattle/Tacoma - 1.6%
#15 - Minneapolis - 1.5%
#19 - Cleveland/Dayton - 1.3%
#25 - Portland Or - 1.0%
#26 - Baltimore - 0.9%
#27 - Indianapolis - 0.9%
#32 - Columbus OH - 0.8%
And that does not include smaller defined markets like Milwaukee, Cincinnati, Dayton, Green Bay, Des Moines-Ames, Flint, Toledo, Madison WI, Decatur, Champaign .. all between 0.30% and 0.75% shares each.
The Big Ten has a total college sports media market lock in the 3 largest markets, total 14.3% of the total national market. as well as a total media market lock on the other 10 markets listed above total almost 12% ... which means just those listed markets (13 ) represent 26% of the USA media market share - not including the many smaller markets (which probably add up to another 10% - 12% of USA's media market share). I do not think ANY other conference even totals as much as 15% including ALL their markets.
