In the eye-opening trailer for the documentary Lo and Behold, Reveries of the Connected World, internet pioneer Leonard Kleinrock takes us to room 3420 at the University of California, Los Angeles — the birthplace of the internet. He shows us the first piece of internet equipment, the "military-hardened" machine from which the first-ever message was sent. "A revolution began," Leonard proudly proclaims. Acclaimed director Werner Herzog takes us into an in-depth exploration of this "revolution" called the internet, from its inception, to its meteoric rise, to its "greatest glories," all in an effort to examine what this explosion of information means for our modern society.
