1. Beer and pickup truck commercials were the norm when fans were younger.
2. A decade or two later, you started to see ads for luxury cars and pharmaceuticals all over the TV during an NFL game. This wasn't because the NFL suddenly decided to market itself to newer, older fans. It was their traditional fan base simply getting older.
3. Now that traditional fan base is dying off, and those that remain are likely to be found in nursing homes.
The homosexualization and feminization of the NFL today reflects the sobering reality they're facing: Young heterosexual men aren't big football fans anymore. So the NFL has a desperate need to replace their traditional fans with other customers -- many of whom aren't even football fans at all.
Interesting, well-reasoned point.
