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
No, because your smartphone needs internet, tv signals reach way more places, and more reliably.
Especially since broadcast tv, in America ya damn Limeys, is free, while internet is either very localized (WiFi, etc…) which may or may not be free, or wide spread (Cell phones, Satellites, etc…) which are definitely pay.
I know it's semantics, but if your great-gramps would time travel to today, he would ask about your pocket TV, and you would reply nah, it's a smartphone
