During the Tokyo Olympics, gymnast Simone Biles dominated among U.S. Olympians in the number of times her handle was mentioned on Twitter, a Pew Research Center analysis found. Of the more than 2.1 million tweets that mentioned the handle of any U.S. Olympians during the Games, Biles’ account was referenced in more than 650,000 tweets, or 31% of the total. Also, just three sports – gymnastics, basketball, and track and field – produced the vast majority of individual Team USA athlete mentions on Twitter. Athletes from these three sports accounted for 79% of all mentions of U.S. Olympians during the Games.
