Barack Obama has broken three social media records after winning the US Presidential election last night, Guinness World Records has confirmed.
Obama's tweet "four more years", accompanied by a photograph of Obama and wife Michelle, posted at 5.16pm (NZT) has become the most popular of all time, breaking the record for the most widespread social networking message in 24 hours.
The message was retweeted more than 687,429 times within 24 hours of posting last night, Guinness World Records said.
At 7.46am (NZT) it had been retweeted 703,915 times and had 242,370 votes as favourites.
It has easily beaten the previous record for most popular tweet set by pop star Justin Bieber on his 18th birthday.
His birthday message was re-posted 251,878 times on Twitter and Facebook by different individuals within 24 hours of its first appearance on March 1.
And Bieber's 'RIP Avalanna. i love you' in September only had 223,376 retweets.
Obama also smashed two Facebook records. A post made on November 7 on Obama's official Facebook page received the most likes on a Facebook ever, doubling in less than 24 hours the previous records of 1,662,336 and surpassing by four times the record for most likes on a Facebook item in 24 hours, which stood at 588,243.
Editor-in-Chief Craig Glenday said: "Obama did more than just beat Romney; he also ousted Justin Bieber from the Twitter top spot and broke the most significant social media records to date."
"Browsing through the comments on Twitter and Facebook, it's clear that it's not just Americans who are overjoyed at Obama's victory last night - the world has tweeted and posted its support for the President's second term.
"These incredible stats - a snapshot of opinion from around the world - are a testament to the President's global popularity and a demonstration of the importance and power of social media in modern politics," he said.
The final figures that will enter the record books will be confirmed by Guinness World Records after the 24-hour period is finalised.
