If you count Sirius + XM subscribers, there's about 18-20 million, right? I know there's people that subscribe to both, and the fact that unsold cars actually count towards the count, so I'm aware of how unaccurate that number is. But, i'm watching the Ohio State - Michigan football game, and they just said that there have been about 7.527 million fans have watched OSU v Michigan in person since 1927. You'd have to take away 4-6 MILLION satellite radio subscribers, and you'd still have double the number of people who've seen OSU v. UM since 1927. Interesting.
