Because of smartphones, pocket TVs were never a thing.
As a kid I imagined the future as being able to hold a TV in your pocket, and flying skateboards. For the latter I guess electric scooters will have to do
I thought it was random as fuck when I worked at Walmart, I was asked to clean out the traps in the freezer (like a liquid channel for spills) and I found a pocket TV from the 90's stuffed in there, still in the packaging. This was only a few years ago; that thing had to have been in there for at least 2 decades.
Not a pocket tv, but we had radios that picked up tv signals. Those were pretty popular. We had several when i was a kid. You could still buy them fairly recently - before the digital thing. We used to take one camping for local weather reports.
What are you even on about? I have a screen in my pocket where i can watch quite literally every movie that exists.
Imagine being a time traveller and someone asks you if you have any cool tech like a pocket tv.
"Hah, no kiddo, we dont. I have that screnn with access to movies and tv shows tho."
I used one as recent as the mid 2000's. There was some sporting event going on (probably women's world cup) and I wanted to watch the game while playing in Ultimate league. Streaming wasn't as prevalent as it is now and the game was on OTA channel.
