When president Obama was elected in 2008 many cited his use of social media tools such as Facebook and Twitter - then still a growing site treated with bemusement by many - as a key strategy in winning the race to the White House.
Come 2012 and Twitter is now a far more established and respected medium, with candidates in both parties using the site to drum up interest in their campaigns.
With all eyes on the elections on Tuesday night it was no surprise the site was a key location for many following the results as they rolled in across the country, with users of the site smashing existing Twitter records in the process as the wrote about the unfolding events.
"As the results of the election were called by news organisations, the conversation on Twitter surged, hitting a peak of 327,452 tweets per minute," wrote Adam Sharp, head of government, news and social innovation at Twitter.
"Before President Obama took the stage to address the nation, he shared a special update on Twitter. As thousands of supporters cheered in Chicago, more than 455,000 (and counting) retweeted his celebratory message."

At the time of publication the message has now been retweeted some 531,000 times, underlying the huge reach of Twitter to spread messages. It has also set a new record for number of times a message has been retweeted.
Twitter was also used by other leading world leaders to congratulate Obama on his victory, including the UK's prime minister David Cameron.
Warm congratulations to my friend @barackobama. Look forward to continuing to work together.— David Cameron (@David_Cameron) November 7, 2012
No doubt this will be followed up with a good-old fashioned phone call on the red telephone linking the Oval Office to Number 10 Downing Street.
