It wasn't in a speech or a statement that Barack Obama announced that he was going to be re-elected as the president of the United States. It was through Twitter.

At 11:14 p.m. ET, @BarackObama tweeted, "This happened because of you. Thank you."

A few minutes later: "We're all in this together. That's how we campaigned, and that's who we are. Thank you. - bo."

And finally along with a photo of him and Michelle Obama: "Four more years." That last tweet is now his most retweeted tweet and one of the most retweeted tweets ever. Twitter would not confirm if it was the most retweeted tweet ever. Just 40 minutes after posting it, it had 308,705 retweets.

According to Twitter, after a network call of the presidential race at 11:19 p.m., there were 327,453 tweets per minute. On Election Day itself there were over 20 million election related tweets. For more on the social media reaction to Election Day, check out our guide.
