From the edge of space to the top of our Viral Chart, it's been a week of dizzy heights for fearless skydiver Felix Baumgartner and his sponsor Red Bull.
The Austrian daredevil's record-breaking jump from 128,000 feet above the earth had already been watched live by an audience of 8 million on YouTube. And now it takes the top spot in our Brand Chart after being shared more than 150,000 times by people wanting to relive his dramatic descent.
The top spot in the User Generated Content chart this week goes to another daredevil - although this one's a little closer to terra firma. Martyn Ashton's brilliant bike stunts, shared more than 200,000 times, push an awesome Lego recreation of the Stratos jump into second place.
The charts are compiled with the Viral Ad Network and are based on the number of shares each video has received on social media over the last seven days.
