But if one is less myopic, and considers aspects of the real world other than one product form one company, the answer is different.
If one looks at the vast majority of screens produced in the last 5 years, one does NOT see any aspect ratio except one: 16:9.
4:3 is used infrequently on some bizarre niche products. It is also used on one popular product.
Go to Amazon. They sell 1,278 TV sets with 16:9 screens, and 131 with the old aspect ratio.
They sell 18,923 different computer monitors. They don't list 4:3 as a choice, so I assume that none of them have anything but the standard 16:9 aspect ratio.
It would be truly bizarre to buy a 4:3 computer monitor. I doubt that old-fashioned stuff is even still in production (except for some bizarre, niche products).
