It would help, in general, if you spent less time speculating in your responses and more time researching them and presenting actual arguments and evidence.

Let's go with the highest possible amount of money they could get according to this: $200. (They won't get that with 40k subscribers....I assure you)
According to estimates, an average baseball game has about 32 minutes of commercials. In 30 second spots, this would be 64 ads per game. That would be about 11,000 commercials throughout the entire season. At the elevated price of $200 that would be roughly 2M.
So....no. No that will not pay 3/4 of 50M. And go ahead and wildly inflate/double/change those numbers all you want, you'd have to multiple by them by several factors to even get close to such a price tag.
