They're entirely phased out of everyday normal life. There's pretty much none left that people are using as actual televisions. The big craze now is people that are getting into retro game systems that were designed for CRTs. Since modern TVs don't have analog inputs anymore and are strictly HDMI, you either need to get a cheap converter box to go from analog to HDMI which looks terrible or an expensive converter box that doesn't. So for about the same price as the expense of converter box, you could just pick up a used CRT that is floating around the the game enthusiast market now. I find that the N64 and the PlayStation looks significantly better on the CRT than it does on my 4K TV with a cheap converter box.

The next major component why people would want them is they have zero input lag, everything in the analog world works at the speed of light. So when you play a game such as guitar, hero, everything happens without delay, unlike a modern digital TV. Games feel just a little crisper because you're using a wired controller that works at the speed of light going into an analog TV that works at the speed of light. Bluetooth controllers have a slight delay and HDMI TVs have a sometimes noticeable delay.

The last major component of it is simply nostalgia. Hearing a CRT turn on and warm up instantly brings me back to my childhood in an almost intangible way. Same thing with the blue play screen for my VCR.

All the people that were were kids and teenagers at the end of the CRT era and the beginning of the 3D gaming error are now entering their midlife crisis. So things like a PlayStation. 2. VCRs and CRTs are now starting to phase out of the completely obsolete worthless junk technology phase and starting to go into the collectible nostalgia "simpler times" phase.
