Why are there no tube televisions anymore?


It’s funny when you come to think of it and compare video with audio. How come in the audio world discussions sometimes become intense, while there seem to be far less intense discussions in the TV & video realm?

With TV’s there’s no talk on tubes, transistors, analog, digital, vinyl, cables, power cords, heck we can even get ’audio’ fuses and -USB cables.

No one has a tube TV (while they really have a ’warmer’ image :) and very few people use a $400 power cord with their TV set. And while there are expensive HDMI cables on the market, the vast majority uses one below $50. And no one spends money on floor spacers to avoid cable vibrations.

Our eyes may even be far more sensitive than our ears ... yet discussions are far less intense. How come?

@tim_p - I had one of those Pioneer Kuro plasmas, too; it was wonderful and yes, those were about as 'true' blacks as you could get at that time... Now I use TOTL Sony OLED, and yeah, it's even blacker! 
Rudy, technology dies when it is ousted by better technology.
viz horse and cart vs car
     CRT vs flat screen
     VCR vs DVD
     bow and arrow vs rapid fire automatic rifle
     etc.

Valves and vinyl have not been driven from the market because there are no newer technologies that are clearly better.

Sound is created through mechanical actions, ie. vibrations. Audio begins with the microphone and ends with the speaker. Everything in between matters but is not seen. Same with video: it begins with light and ends with light. Everything in between matters but is unseen. Wow! Must have been that cheesecake last night.
My point is no matter the technological advances audio will always begin and end with electromechanical interfaces and video with electro optical. 
Perhaps consider also that today’s TV take up much less room, produce almost no heat, come in many more sizes for convenience, at almost every price point look better, use way less energy and are able to display higher quality images than earlier technologies. TV are mass market and world wide items. By comparison the audiophile market is tiny. Almost every aspect of video delivery to the user is also regulated and homogenized to one size fits all by the government. If we look at it from the hardware side, audio is one of the few product lines where technologies doing essentially the same thing exist side by side in the marketplace. Audio is quite unique.
