When I worked in the Electronics department at Venture circa 1980, we used to sell "camping televisions." A box about the size and shape of a small computer tower...mostly a heavy small battery and an oldstyle TV screen (B&W, of course) of 4 inches. I have no recall of what they cost, but they weren't cheap. We didn't sell a lot of them, but they'd on occasion go on sale, and in a week we might sell four or five.
At the time, I could not believe that anyone would want to watch a tiny screen while camping. I asked several, and it was always men, who explained that they wanted to be able to watch games while at their campsite (c'mon guys, ever hear of radio?). Most of these were people for whom camping was a popup, camper, or RV, and so they ran generators at least part of the time.
I now see people watching movies, TV shows, Youtube, etc., on little tiny screens. I still can't believe people LIKE even the vastly superior images that you can get on a phone, that are still so tiny...
However, I really started to feel older after I started teaching, when students were familiar with shows like Gilligan's Island or Andy Griffith because they've been in reruns on Nick at Night or whatever, but had never seen a popular movie from a year or two ago...
And the fact that they couldn't understand 4 TV stations TOTAL, no home computers or internet, and phones that plugged into the wall, and you had to sit or stand within whatever length of phone cord you happened to have...
