Minutes later, as his supporters cheered boisterously in a packed Chicago arena, President Obama's Twitter account posted a message with just three words and a picture.
"Four more years," the tweet said. The attached picture showed a happy Barack Obama embracing his wife and First Lady Michelle against a cloudy backdrop.
In just a few short hours, the President's tweet became the most popular message of all-time on Twitter, the six-year-old microblogging site. As of Wednesday morning, that single tweet garnered 654,836 retweets and 222,405 favorites.
The Obama campaign released two tweets prior to releasing the viral photo, one of which was confirmed to have been written by the President himself.
The first tweet, sent at 11:14 p.m. EST: "This happened because of you. Thank you."
The second tweet, sent one minute later at 11:15 p.m. EST, included the President's signature: "We're all in this together. That's how we campaigned, and that's who we are. Thank you. -bo"
Both of those messages garnered more than 150,000 retweets and 50,000 favorites.
The Obama campaign hasn't released a single tweet since "Four More Years," however.
That record tweet, which has not yet been officially confirmed by Twitter, has apparently beat out the two former record-holders by several hundred thousand retweets.
Those record holders, pop singer Justin Bieber and fast food chain Wendy's, both earned more than 200,000 retweets apiece. Bieber had tweeted "RIP Avalanna. [sic] i love you" after six-year-old Avalanna Routh, a fan of Bieber's died of cancer in September. On June 8, 2011, however, Wendy's earned more retweets by promising 50 cents for each retweet to "help kids in foster care," following its message with the hashtag "#TreatItFwd."
Election Night was a big success for Twitter, which saw the conversation on its microblogging platform surge at 327,452 tweets sent off per minute. Twitter detailed several other spikes in traffic when news stations called the presidential races in Iowa, Pennsylvania and Wisconsin, as well as when the polls closed on the East Coast for the first time.
More than 31 million tweets were posted on Election Day 2012 alone.
