Red Bull Stratos Space Jump

No. 6: Felix Baumgartner's 128,000-foot freefall from the stratosphere was watched by 8 million live viewers on YouTube, making it the most-watched live stream at that time. Red Bull generated brand value equivalent to $6 billion in earned media for a $65 million investment. This is over 50 times more cost-efficient than the average Super Bowl ad, proving content marketing can replace traditional advertising entirely.
