Still, I have to say this all moved faster than I thought it would. I marvel to think that it was just a "few" years ago we, as kids (I'm 38 now), had 3 local VHF broadcast stations. It was huge when dad put up a taller antenna and we got Fox 17 (UHF) out of Nashville! Fox had the best cartoons, of course. We consumed our movies on VHS. We were bound to the broadcasters' schedules and "slaves" to the TV Guide. DVD came along and was a revelation in appearance and convenience. I skipped the HD format war and only got into Blu-ray a couple of years ago. Watching a Blu-ray now is basically like having a 35mm release print in your home! To me, the time from Blu-ray at 1920x1080 to 4K UHD seems rather short compared to the time between all the other changes.
The best change is video streaming. After watching Hulu and Netflix during the last few years there is no way I'm going back to watching TV. Yes I do have a TV but I only use for Blu-Rays and hooking up computers that I'm working on to it.
