There's no denying that social media has played a huge role in the London Olympics. Compass Labs analyzed Facebook fans of the Official Olympic Games and US Olympic Team pages to analyze how the two groups match up. Compass Labs cross-referenced Likers' other favorited Facebook pages to find which sports, movies, brands and TV shows rated highest with each group. The two pages have similar demographics, with the top age group being ages 18-25 and the top gender being female. US fans like track and field the best, but general Olympic fans don't have track and field in their top five. Among individual athletes, however, swimmer Michael Phelps tops the list for both groups.
