Twitter said activity during the game — a 2-2 draw that saw Chelsea progress to the final after winning the first leg in London 1-0 — peaked at 13,684 messages per second. That beat out the previous record for a sporting event, the 12,233 tweets per second during the climax of February’s Super Bowl between the NFL’s New York Giants and New England Patriots, which saw New York win 21-17 after scoring a touchdown with less a minute remaining.
