Twitter expects the World Cup to be the most tweeted event in history

When you walk around the offices of Twitter’s engineering department, located on the sixth floor of the company’s downtown San Francisco headquarters, you will see signs counting down the days until the World Cup. The World Cup is the world’s biggest sporting event, and because it consists of fewer matches than the Olympics, it generates more Internet traffic, in shorter bursts. More than 3.2 billion people watched at least a minute of the World Cup live in 2010. For Twitter, Facebook, ESPN, YouTube, and a host of regional social media sites from Brazil to Russia, the World Cup means engineers frantically working overtime to prevent outages and site overloads.
