Twitter on Tuesday announced the events of 2011 that generated the most tweets per second. No. 1 on the list was the MTV Video Music Awards, when Beyoncé revealed she was pregnant. Some 8,868 tweets were recorded for that event. By contrast, while the Super Bowl on February 6 drew the biggest television audience in history -- 111 million viewers -- its tweet-per-second count came in at 4,064 -- in other words, less than half what the VMAs produced with 11.4 million. Another TV awards show, the Bet Awards, on June 27 also scored strongly with 6,436 tweets per second. That beat out the NBA Finals Championship on June 13 with 5,531 tps, the Japanese earthquake and tsunami on March 11 with 5,530, and the raid that killed Osama Bin Laden on May 2 with 5,106. But it was topped by such events as the execution of Troy Davis on September 20 with 7,671 tps, the resignation of Steve Jobs on August 25 with 7,064, and Jobs's death on October 6 with 6,049.
