They've been called the first "Social Games" — and the London Summer Olympics have delivered on that promise, making social stars out of athletes like gymnast Gabby Douglas, who saw her Facebook fanbase grow by nearly 4,000 percent during the games.
Gymnasts Marcel Nguyen and Jordyn Wieber were also among the big winners on Facebook, according to a research firm that tracked athletes' fan numbers during the games.
Douglas took the Olympics and Facebook by storm when she coolly led her team to an all-around gold and then winning the individual all-around gold, as well.
