After several years in the making, May 2 marked what was billed as the “Fight of the Century” between welterweight boxers Floyd Mayweather and Manny Pacquiao. After organizers announced the match-up in late February, it quickly became one of the most anticipated events of 2015, driving massive conversation on Facebook.
