Most live streams for a single event on YouTube

The official live stream by St. James’s Palace of Prince William’s marriage to Catherine Middleton (both UK) in London, UK, on 29 April 2011 achieved a record 72 million live views, as people from 188 countries around the world tuned in to watch the event on The Royal Channel, the British Monarchy’s official YouTube channel. Although this figure alone was enough to beat the 70 million streams achieved during the inauguration of US President Barack Obama in 2009, the wedding’s overall tally is significantly higher when taking into account the millions watching via other live streaming services.
