Adrian Ballinger and Cory Richards were sponsored by Eddie Bauer to do an Everest climb, and they relayed information from the Everest climb using the smartphone software application and service called Snapchat. Mount Everest has had a 3G wireless data communication network since 2010. This effort was repeated in 2017, Ballinger summitted without supplementary oxygen, but Richards had to resort to an oxygen tank for the final push to the summit.
