It seemed like the inevitable future at the time, we're sure. On April 20th in 1964, Bell Telephone showed off the Mod 1 Picturephone -- a precursor to the Skype and Hangouts video calls that have become a standard but under-utilized feature of modern communications. The demonstration was part of the World's Fair in Flushing Meadows, visitors were able to step into a booth and have a conversation with a person thousands of miles away in Disneyland. But instead of just talking into a handset, users sat in front of an oblong device that housed both a video screen and a camera. The service delivered a 30 frame-per-second black-and-white feed to wowed Fair-goers. A few months later, in June of the same year, AT&T took the service commercial.
