It might not have been as big as 2014, but the last 12 months have been pretty huge for sport.
We've seen Great Britain end a long wait for Davis Cup glory, the United States run riot in football's Women's World Cup, and Floyd Mayweather and Manny Pacquiao meet in the fight of the century.
You couldn't log on to Twitter when these were going on without reading a flood of tweets about each event.
One of them must have been the most tweeted-about sporting event of the year, right? Guess again.
Maybe it was the Super Bowl. It's easy to forget about stuff that's happening while us Europeans are fast asleep.
Or the Champions League final, perhaps. People can misjudge how popular that gets too.
Close, but no. It was actually the Copa America, with a remarkable 14 billion impressions. Not million. Billion.
Sure it had it's moments, like Neymar's meltdown and
Gonzalo Jara's bum-gate, but 14 billion?!
