Two billion people around the world tuned in to watch Kate and William tie the knot on TV last week. But judging by early online figures, the death of Usama bin Laden is a much bigger event -- at least for web users.

At 12.30 a.m. EDT Monday morning, almost one in five updates posted to Twitter worldwide included the word "osama,"according to analytics tracking website Trendistic. At the peak of the royal wedding ceremony, the number of updates mentioning "wedding" was almost one in ten.

Searches related to bin Laden and President Obama also dominated Google searches this afternoon.
