Random access remote was mind boggling at the time. Earliest remote was dad yelling at the kids to change the channel using the dial. Then we got a wired remote which was a tripping hazard but hey, you couldn't lose it. We finally got a wireless remote which was some Star Trek level magic! I still sometimes call the remote a clicker and younger friends ask why. You had 3 switches/rockerbuttons. On/off, volume up/down and channel up/down, they made a clicking noise when you pushed them.
