In that cubicle by the water cooler you see him: your employee, on your dime, tilted back in that pricey Herman Miller chair, his personal smartphone in hand. Judging by the furrowed brow, you'd guess it's a hot game of Words With Friends.

The whole beauty of fantasy sports is that you can manage teams of pro athletes without ever leaving your couch. The process of drafting teams, betting on the success of individual players and trash-talking with your similarly obsessed friends takes place on Web and mobile platforms, and that makes the fantasy sports pastime about more than just bragging rights. It's become a billion-dollar business.
