Die?
A) Popular things may become less popular. This may tend to be associated with a decline in industry frenzy around them.
B) Common technologies may be phased out of mainstream use, or even discontinue in production.
I’m guessing you sort of mean A)?
Screens that show moving pictures. are going to continue to be popular, perhaps forever, even after 3D VR smellivision is a thing. Not everyone wants to be immersed even to the extent of looking at simulated 3D images. Most people I know tend to go to the 2D versions of movies.
But I’m also guessing you mean broadcast TV, presented as ongoing channels.
I expect that is going to go down and down in popularity, but I don’t know at what rate. It seems to still have appeal for some people.
The main advantages it has over Internet streaming video, is the lame streaming and buffering systems, browser issues, ISP performance, and brand name recognition and investment in producing non-stop attention-grabbing crap er, I mean “content”.
But I haven’t lived with TV for nearly ten years, and it wasn’t my choice to do so then, either. I like to choose what I watch, watch it from the beginning, be able to stop and pause and rewind, and not be subjected to commercials.
Also, modern TV services are starting to try out the Orwellian Mind Screen thing of watching you and tracking what you watch, even listening for what keywords you might say, so the marketing Borg can try to seduce you into more purchases of advertised goods and services. Those people are evil and should all be tortured and killed. ;-/
