As Felix Baumgartner rose in his balloon, so did the number of viewers watching on YouTube. Nearly 7.3 million watched as he sat on the edge of the capsule moments before jumping.
The figure is a record for live video on the site.
After he landed, Red Bull posted a picture of the skydiver on his knees on the ground to Facebook, generating nearly 216,000 likes, 10,000 comments and more than 29,000 shares in less than 40 minutes.
And as Baumgartner reached his target height, the project's official Twitter account tweeted a message that has been retweeted over 5,000 times:
Decisions has been made: Baumgartner will jump. http://t.co/rf5aDN7D
Felix Baumgartner's body pierced the atmosphere at speeds topping 700 miles per hour, appearing to achieve another of his goals: to become the first skydiver to break the speed of sound, according to the project website.
Baumgartner also broke records for the highest altitude manned balloon flight and the highest altitude skydive before landing safely on the ground and raising his arms in a victory salute about 10 minutes after he stepped into the air.
Congratulations to Felix Baumgartner for an outstanding, inspiring display of courage. It was a joy to watch. #spaceballs
