As has been stated here often and recently, things change very fast, especially “things.” Check out the old component stereo in today’s classic A&J, from 2001. I know; a lot of you old-timers probably still have one, but I’ll bet your kids don’t. And I’ll bet you wouldn’t be willing to try and make a living selling them. Check out, too, the headphones. We all grew up with a version of them, the larger the better. They sounded great, even if you wanted to listen to nothing. The better ones were capable of shutting out any outside noises. True, they were not very portable—unless you really did want to listen to nothing.
