As audio/video systems have advanced in performance, features, and capabilities, they have also become increasingly more difficult to operate. Back in the day, a TV was just a TV, with a single remote control and about 13 channels to navigate. You pointed the remote at it, and if it didn’t work, you changed the batteries. A sound system had an input selector to choose what to listen to and a volume knob to make the music louder or quieter.
