>Yes they are here but not nearly as common as content delivered in ancient formats from over a decade ago. For example go on a wallpapers subreddit, the vast majority is still in 8-bit 1920x1080 JPEG. Video is still mostly 1080. The leading music services still deliver in 2-channel lossy formats. And this is 2016.

Ever experienced YouTube buffering on an average connection? And that's for the metropolitan US -- consider the developing world, or even rural US, the mobile internet caps, etc.

Not to mention that even if you have enough speed, still you don't get much benefit from 4K video for 99% of stuff out there. Diminishing returns. I should know, I have projected good 1080p video to movie theaters, and nobody would call it bad or inadequate. On an average 15-27" monitor? It's not even an issue...

The rest of the world doesn't matter. If there is sufficient demand for 4K video and faster connection speeds, there will eventually be a product for them.

Said the American. In fact, probably the US doesn't matter in this regard, as it has lower average speeds than most of Europe and SE Asia.
