The record-breaking time Obama managed to set was "less than five hours", according to Guinness officials, smashing the old record held by Robert Downey Jr. of 23 hours and 22 minutes. However the @POTUS account currently lags behind @RobertDowneyJr for total followers, at 2.1 million versus 4.5 million.
The record for fastest time to one million followers isn't the only record President Obama holds. His other account, @BarackObama, has the most followers of any politician at nearly 60 million. The tweet of Obama and his wife embracing after his 2012 re-election is also still in the top three most retweeted tweets of all time.
The new @POTUS account will be directly controlled by Obama himself, with the White House confirming that tweets from the account will be "coming exclusively from him". Obama also said that "the handle comes with the house", indicating control will transfer to the next US President following the 2016 presidential election.
