Didn't have to compete with HD widescreen broadcasts of just about every home game back then.
Advances in both television technology and distribution rights have forced teams and owners have to rethink the fan experience.
A cold hot dog, 2 beer choices, and a backless seat no longer cut it.
I don't disagree that you've probably tapped into the motivation here, but I come at it from the opposite point of view. I went to Met Life Stadium a few weeks ago for the first time (neighbor's consultant gave him four seats/parking/all that jazz, for free). I thought it was one of the worst places I've ever been. For all the suites and luxury items, I would just as soon watch the game from home.
Give me the backless seats (OK, I'll take a seat-back) in a place that let's me feel like I'm actually there and I'm happy - much happier than I was at a place like Met Life. And I'm only eating hot dogs there anyway (apart from the tailgating experience).
To me:
Fenway Park > New Yankee Stadium
Rutgers Stadium > Met Life Stadium
The Palestra > Barclays Center
