Sunday night, President Obama announced that Osama bin Laden had been killed in Pakistan by U.S. forces. As the news broke, searches for videos about the story -- "osama bin laden dead" -- were by far the top rising terms on YouTube. Other top searches were for songs including Toby Keith's "Courtesy of the Red, White, and Blue," "Good Bless America," and Lee Greenwood's "God Bless the U.S.A," among others.

One of the top trending videos on Twitter was President George W. Bush's famous bullhorn speech from ground zero in 2001.

After the announcement, YouTube began seeing a surge in videos uploaded of both YouTube user reactions and on-the-scene videos from gatherings and celebrations around the country, including at the United States Naval and Air Force academies, Ground Zero, and a number of universities, which can be seen in the playlist of clips below.
