Money from every game being on TV, that drives the entire economy of sports, is more the demise than the TV itself. There is an atmosphere you simply can't replace, but if you're going to charge thousands for a product then that product better be desirable. It's fair for some would be attendees to say that the product hasn't delivered.
Convenience is sort of a weird thing in regards to sales. Online connectivity has made video game sales high, yet the missing social interactions of being next to the other player has helped people rediscover board gaming. The unmatched convenience of ebooks should have driven paper books away, yet it can't. Same for music streaming and vinyl. There is just something to be said for factors other than convenience. While TV has similar convenience to these other things, you can't match the deafening roar of the crowd on a kickoff return at home like you can at the stadium.
