When Ellen DeGeneres tweeted a selfie featuring several A-list Hollywood celebrities during the 2014 Oscars, she almost "broke" Twitter. Her tweet broke the record for most retweeted tweet of all time -- Barack Obama’s “Four more years” tweet on Election Night 2012 -- in less than an hour.

Ellen’s Oscar selfie crossed the 781,832 RTs mark in about an hour, and has been retweeted more than 3 million times as of noon Tuesday.

Here’s how that moment went down, in a Twitter map. Twitter’s data editor, Simon Rogers, plotted every single geotagged tweet about the Oscars in an interactive timeline map. Ellen's Oscar selfie tweet went out at 22:00, so watch for that moment!
