Red, white and blue against black, yellow and red? Try neon reds and greens. If you tweeted about the game during Tuesday’s World Cup match between USA and Belgium, Twitter labeled your geo-tagged tweet red (if you were talking about Belgium) or green (if you were talking about the U.S.) and detected you on a color-coded, real-time global heat map. Some 9.1 million tweets were sent out during Tuesday’s match, a victory for Belgium. Twitter used keywords and World Cup-specific hashtags to track the tweets in real time. At 19 minutes and 1 second into the game, the map surges with an influx of red: a goal for Belgium. Twelve seconds later, another red surge: Belgium’s second goal. Seconds later, USA scores and green illuminates the map. Popular hashtags during the game included #BELUSA and #TimHoward.
