Why are there no tube televisions anymore?

I got rid of the VCR and tapes long ago! I have a nice collection of movies on DVD. When I saw the first DVD players back around 2002 I knew that was the future! And they played CDs too!

Tube TVs like tube amps, 35mm film, and vinyl are objectively inferior to modern replacements. However, all of them provided excellent quality and remain perfectly enjoyable today. My mother still has a Panasonic 20" TV I bought back in the 1990s and it is still in regular use. The colors don't seem to have faded even though she often leaves it on through the night as she falls asleep. When viewed at a typical distance it still looks great. My previous TV was a 34" widescreen tube with 1080 resolution. It had a great picture for watching movies. It was a little warpy around the edges which was noticeable on news banners and video games. That TV had a digital image processor so it was a hybrid of sorts. The gamers like the pure analog sets because the lag time is practically non existent, although frame rate ultimately sets the gaming lag and with modern 120Hz displays and gaming systems the lag is down below 10 milliseconds, which is from a human perspective pretty much non existent. 

Well, it's just a matter of time, as technology progresses.
For example Alienware 27 Gaming Monitor (AW2721D)
a 27' 2560x1440 IPS gaming monitor with... oh yeah, this is impressive
240Hz.

Remember the Quasar, "works in a drawer" TV's?  They had a literal slide out cabinet with the circuit boards in a row like files.  I recall reliability was poor due to the bad connectors at the base of the boards.  So ironically, easy to work on which was good since they needed servicing often.  The good old days- AM tube radios, car tires that lasted 5000 miles, oil changes every 1500-3000 miles, carburetors (good luck starting on cold mornings) but also we had soda fountains, juke boxes and roller skating rinks.  Real movie theaters...

I had one of the last widescreen 16:9 tube tv’s back in 2001, the Toshiba 34HF81, beautiful TV, even supported a Klipsch KLFC7 centre on top. Along with those huge projector box tv’s, and the lcd/plasma. That was my last tube TV, the next plunge was probably the best, in the Pioneer Kuro plasma at that time, blacks were a "true" black. Now using the last of the plasmas made in the Panasonic 65VT60 and still love it.
