Video from the phone

Television proved it was possible to send moving pictures along wires. This raised the further possibility of what had always sounded like a great idea - videophones on which callers could see as well as talk to each other. But there were some problems with that vision. There was a technical problem. Television pictures carry a lot of signal information - more than ordinary phone lines can accommodate. There was a human issue, too. The truth is that people don't always want to be seen on the phone. But it took the pioneers of videophones a little while to learn that lesson.
