You may complain that I've chosen a soft target, and that if I'd taken a pin-sharp image and scaled it, I'd have got worse results. That's true. But digital video for broadcast or blu-ray is a lot softer than people imagine. That's why TVs have a sharpness control.
Though 1080p resolutions represent the next step in high-definition video, standards for the format have yet to emerge and no one’s really figured out how to distribute video, with its massive file footprint, efficiently and cost effectively. How exactly does one distribute files that can run to hundreds of megabytes?... Given that uncompressed 1080p footage has a bit-rate of about 75MB/s, and even the fastest hard drives operate at only about 35MB/s, compression isn’t merely likely, it’s necessary.... Kotsaftis says manufacturers will probably begin shipping and promoting larger TVs. 'In coming years, 32-inch or 36-inch screens will have become the sort of standard that 28-inch TVs are now. To exploit 1080p, you need a larger form factor. You’re just not going to notice enough of a difference on smaller screens.' The same quality/convenience argument leads him to believe that physical media for 1080p content will struggle to gain traction among consumers. '1080p implies going back to physical media. Even over the Internet, it’s going to require massive files and, given the choice, most people would happily settle for a 480p file anyway.'"
TLDR; old man doesn't like change.
Okay, that's just me being a little bit facetious. But honestly, this part:
Given that uncompressed 4K footage has a bit-rate of about 600MB/s, and even the fastest solid-state drives operate at only about 500MB/s, compression isn’t merely likely, it’s necessary.
...is just stupid. Why would anyone think uncompressed was ever even under consideration?
This means scaling up or down will work very well and people won't be able to tell the difference between this and 1080p.
I don't think pixels work the way you think they do.
That aside, you may not realise that most 1080p TVs, by default, scale up the image by about 5%, and yet that somehow doesn't look "smeared to shit." For any natural image source the difference is marginal at worst, and probably likewise for any digitally originated images, since broadcasters deliberately keep them soft for a variety of reasons.
And yes, I'm claiming industry-wide effort to make 1080 appear visibly better than 720.
You do know that it's also actually better than 720p too, right? The clue is in the numbers.
I still remember with bitter disappointment the day I discovered that the 30cm on one edge of my ruler didn't exactly line up with the 15" on the other side after all.
Why does there have to be a physical representation for this extra money? What stops a government just saying "we've now got $1tn extra dollars"? When did money, which is an abstract concept that we humans invented, get so out of our control? Or would it just not work any other way?

I used to have an actual 720 DLP TV and it looked quite fantastic compared to the 768 LCD that replaced it, and that's not due to the tech difference.
How can you control for the difference in technology when making the comparison?
This is why many people see a difference between 1080 and 720 TVs
That's far more to do with the fact that a 720p TV only has 66% of the pixels and that 720p TVs generally use much cheaper components all over.
Try rescaling a nice clear image by 16/15 and see what happens.

Oops. 12".
