Too bad social media wasn’t around in Evel Knievel’s day. Tightrope walker Nik Wallenda and his 1,400 foot “Skywire” scoot 1,500 feet over the Grand Canyon sans safety harness drew a flurry of online action for Discovery Channel Sunday night. During a post-walk Wallenda interview with the Today Show‘s Willie Geist and Natalie Morales, the network revealed that the feat, broadcast live in the US and 223 countries, generated 40,000 Tweets per minute, 700K Tweets in total, and 1.5M streams on Discovery.com. Even CNN‘s Piers Morgan was impressed. Tweeted @PiersMorgan: “Now THIS is cable news #skywire.”
