President Obama's announcement that Osama bin Laden was dead had more television viewers than either of his two State of the Union addresses.

There were 56.5 million viewers watching the president's last-minute speech Sunday night, according to ratings reports. That's about twice as many as the 25.6 million who watched Obama's speech announcing U.S. intervention in Libya.

It was also more than the 48 million viewers that watched Obama's first State of the Union address in 2010. His second State of the Union address, this year, had 42.8 million viewers.

Obama's Sunday announcement was carried on nine television networks.
