Video Conferencing

Phone calls. With pictures that move. Check out Google Hangouts for the most popular version.

A video conference just involves cameras from a few or many disparate locations (with excellent internet connectivity), all feeding into one central server and then being replicated or published to receptacle ports remotely. If you haven't seen a broad, multi-prong conference at work, check out The Brady Bunch opening from 1971 and you'll get the gist.
