Hollywood titan James Cameron is the latest Twitter user to take the ubiquitous online message service to a new frontier. In his case, it was nearly seven miles below the ocean surface on March 25, when he descended to the Mariana Trench in a one-person dive craft. Before Cameron, however, others were taking Twitter to extreme locales, from outer space to breaking news to politics. Here's a brief history of some of the more interesting places whence tweets have issued.
Movie mogul James Cameron, the director of Avatar and Titanic, reached the deepest spot on earth, Challenger Deep, located in the Mariana Trench about 300 miles southwest of Guam. From his one-person submersible at a depth of 35,800 feet on March 25, Cameron sent this tweet: "Just arrived at the ocean's deepest pt. Hitting bottom never felt so good. Can't wait to share what I'm seeing w/ you." Cameron's dive was only the second manned mission to Challenger Deep since a 1960 U.S. Navy effort. Cameron's interest in ocean depths stretches to at least 1989, when he wrote and directed The Abyss, a sci-fi suspense film about the hunt for a sunken nuclear submarine.
