More than 8 million people tuned into YouTube to watch Austrian Felix Baumgartner jump from 128,000ft above New Mexico.
The Red Bull Stratos jump - which finally got under way on Sunday after a week of delays - saw the 43-year-old break several records, including the highest ever skydive.
The feat smashed previous records for a single Web video service, which was around 500,000 concurrent streams during the London 2012 Olympic Games.
Video cameras relayed the moment Baumgartner stepped from his balloon capsule to begin his fall to Earth. As the space-jumper neared the final moments before the jump, more and more people tuned in and the numbers continued to climb, mirroring the sky-jumpers ascent.
But it wasn't just YouTube that benefited from the interest in Baumgartner. Moments after Baumgartner landed, Red Bull posted a picture to Facebook. In just 40 minutes, the picture was shared more than 29,000 times and generated nearly 216,000 likes and more than 10,000 comments.
On the way down Baumgartner achieved speeds of over 833.9mph miles per hour breaking the sound barrier in the process.
Baumgartner's jump broke the record that had been held for more than 50 years.
