Oh yeah? In NYC in the early 2000’s we used crude little close circuit TV things. Anyone remember the Remote Lounge?
Remote Lounge could have been cooler, but it played up more of the voyeur angle instead of the communication angle, I felt. (Or maybe that was just me, I dunno.)
Every booth had a cam and a TV, and you used controls to select other booths' cams, pan them around, and watch other people.
