YouTube carried out early experiments with live streaming , including a concert by U2 in 2009 , and a question-and-answer session with US President Barack Obama in February 2010 . These tests had relied on technology from 3rd-party partners , but in September 2010 , YouTube began testing its own live streaming infrastructure . In April 2011 , YouTube announced the rollout of '' YouTube Live '' , with a portal page at the URL "www.youtube.com/live" . The creation of live streams was initially limited to select partners . It was used for real-time broadcasting of events such as the 2012 Olympics in London . In October 2012 , more than 8 million people watched Felix Baumgartner 's jump from the edge of space as a live stream on YouTube
