In some ways I think the times are changing. I've been a Giants fan forever (I guess growing up in the northern part of NJ there wasn't much choice in the matter). For as long as I remember (back to the days of the real LT and the Giants 1st Super Bowl) it was near impossible to get Giants season tickets. Even when they were bad (and they were pretty bad at times) there was a huge waiting list for season tickets. Last night while watching the Giants game they were actually advertising that tickets were available. No, not for this year, but for next year. Why next year? Because next year they open the new stadium and they've basically gone through their season ticket waiting list trying to find people willing to pay the PSL (apparently without that much success). My brother is a far bigger Giants fan than I have ever been was on that list (he's probably been on it for 20 years). He turned them down. They wanted something along of the lines of $20,000 for the PSLs plus $125 per ticket for 10 games per year (pre-season counts too) for a total of about $2500 per year and $20k up-front. These weren't even prime seats or anything.
The Giants are definitely "pricing out" many of their diehard fans. I've had the pleasure to enjoy some rather choice seats at Giants stadium and it is certainly a great experience. I've also sat in the freezing cold in some not-to-great seats. As Jason pointed out above, the home-viewing experience has improved drastically over the years while the in-stadium viewing experience hasn't really changed much. Except for the price. $10k PSLs? I think I'll stay warm and watch it on the TV.
