The news out yesterday that President Obama's confirmation of Osama Bin Laden's death triggered the highest sustained rate of tweets with more than 3,000 sent per second between 10:45 p.m. and 2:20 a.m. EST is not an anomaly.
Google released search statistics earlier this evening that are just as, if not more, impressive. Between 10:30 p.m. and 11:30 p.m. EST on Sunday, Google saw a one million percent increase in searches for "bin laden." The news went out over the official Google Twitter account and linked through to the graph displayed below.
To put things in context, it was first announced over Twitter at 9:45 p.m. EST that President Obama would give a brief announcement at 10:30 p.m. The speech was ultimately delayed until nearly an hour later, but thousands of tweets were already pouring in at this point with guesses as to what the president had to say. For comparison, TechCrunch graphed the Google search spike against another recent spike, that for "royal wedding." On Friday, the royal wedding, it seemed, was the only thing going on; everyone was searching for it. By Sunday, it had been forgotten, eclipsed by much bigger news.
