"Just about dead" is quite the overstatement. They did $32B+ last year in advertising revenue. I hope they do die a quick death, but it's going to be a while before most people cut the cord.
You're dead wrong. U.S. TV ad revenue is shrinking fast > 3% year on year and totals only $67 Billion USD for the entire industry. Also, you're looking at the wrong attribute as a proxy for relevance. The quality of the eyeballs (monetization worth, net worth) and sustained interest are far better on the web and in mobile games. Only a few rare people that don't have computers or smartphones are UHWNIs. So I'll leave that as an exercise for the reader to figure out what kind of customers watch TV.
