And unfortunately, that's about all they're showing on TV.
“There’s no excuse for a “beach volleyball” competition separate from regular volleyball other than to ogle the players.”
Actually the reason that it is in the Olympics is that it draws a higher TV rating in general than the indoor game does. After the dominance of the US Men’s team in the 1980’s an indoor professional league was started to try to capitalize and it failed miserably. The beach game was placed on national TV and the ratings were pretty good until they over-saturated the market.
I’m not sure about the ratings in this Olympics but over time the beach game has proven more popular with the viewing public, probably because the matches are not nearly as long as for any other specific reason. It’s also a FAR easier game to understand for the casual fan than the indoor game is, where if you haven’t played at a high level it would be difficult to understand what each team is trying to accomplish.
