I would characterize it as being dead. I gave up baseball when they started paying players millions to take three swings and sit down. Taking a family to the park became prohibitive so I stopped. Have not been in many years and no longer follow the sport.
I take it, then, that you do not follow the NFL, NBA, or NHL, either, since those sports have ticket prices which are much, much more prohibitive.
Baseball still is the best bargain and the most family-friendly of the four major sports. Unfortunately, my favorite sport is nowhere near as affordale as it used to be. And it has become way, way too commercialized--at the stadium, on TV, and on the radio. Very annoying.
