Why are there no tube televisions anymore?

tonywinga is right. What he leaves out however is he is talking about a notable exception. More typical was all kinds of artifacts, distortions, reliability problems. My dad was at Sears, had friends in the service department, they were always coming out and it was fascinating to watch them demagnetize and adjust one thing after another. Image quality could be exceptional, and that is funny because I remember so well the clarity and color as Kirk wrestled with the Gorn in Arena. https://www.youtube.com/watch?v=4hnBp7x2QAE Or something like that.   

Still happy with the picture from my old school Panasonic plasmas….great mix between detail and warm color saturation….IMO, more like what I see in life than what I get from the newer 4K LED television in our workout room.  Why no tubes - simple, people like flat televisions. BTW, my television cables terminate before they hit the floor.

Motion is still better on CRT sets.

Not so anymore on my 120Hz OLED, no smearing or tearing at all.

I guess most of you got that the topic title was not meant literally. It’s just interesting that there still are tube amplifiers around, and vinyl records, with which there are countless steps (even chemical and mechanical ones) between getting from the studio master tape (where the noise level by the way is the equivalent of 12 bit or less digital sampling) to the final reproduction of sound on your speakers that it’s even astonishing there is any sound quality left. :)  While we can't imagine watching a TV set with tubes anymore.

And there are so many heated debates in the audio world, on how a USB cable or a power cord improved the sound (or not), while these kind of similar discussions are far less with TV’s and image quality. That’s what struck me.

A lot of gamers still prefer CRT sets because of the more fluid motion even than the latest OLED sets.
