Just like 4K tvs. Because of some increasingly irrelevant backward compatibility

2.35:1 - doesn't look like much on an old fashioned 1.33:1 tv screen.

In the early days tv broadcasts were shot on 35mm film. This film used the Academy Standard aspect rato of 4:3 (1.33:1) - an aspect ratio originating in 1892.

Thus tv screens quickly settled on the aspect ratio 1.33:1.

Later, when video and computers were invented, these also stuck to the 1.33:1 ratio of the typical tv.

Yet people wanted to watch movies at home on a wider screen.

The 2.35:1 aspect ratio of The Good, the Bad and the Ugly didn't look like much on an old fashioned tv screen.

Something had to change.

Settling on 16:9 in the late 1980s«

8K resolution (8192 x 4320 pixels), 1.77:1 aspect ratio

In the late 1980s Dr. Kerns Powers cut out rectangles of the extreme and popular aspect ratios of 1.33:1 (television) and 2:35:1 (epic Hollywood movies).

With one piece of cardboard over the other, it was clear that an aspect ratio of 1.77:1 (commonly know as 16:9) would result in the smallest possible borders whether you watched the news or The Good, the Bad and the Ugly.

In the 1990 tv started switching to 1.77:1, the dvd-format settled on 1.77:1 and later, in the 2000s, computer monitors switched to 1.77:1 as well.

Blu-ray, Digital still and video cameras made the switch even later.

But these days the 1.77:1 is the most common aspect ratio.

It is used by HD/1080p tvs, UHD/4K tvs and will also be used in 8K tvs.

The new batch of 8K cameras like the Panavision DXL will also adhere to the 1.77:1 aspect ratio.

The long history of ascpect ratios«

John Hess of Filmmaker IQ has made a long a interesting video about the aspect ratio of movies during the last 120 years.
