A Red Bull-sponsored athlete completed the world's highest-altitude skydive Sunday, ascending to the edge of space in a balloon before hurtling 24 miles back to Earth. The stunt drew more than 7 million YouTube viewers and hundreds of thousands of Facebook likes and accounted for half of all global trending topics on Twitter. "Will the stunt sell more Red Bull? Yeah, I bet it will. And it'll keep people talking for a long time to come," writes Dan Bigman.
