DrDoppio's question was valid and that wiki doesn't really answer it.
There's an assumption that you're capturing video during the majority of the time that the camera is in operation. That is, if you're at 30 fps, most people assume that the shutter is open 1/30 of a second, so anything that moves faster than that is captured as a blur. If you capture 60 fps, the shutter is open 1/60 of a second, so there is less blurring.
However, the two do not HAVE to be linked. it is possible to have the shutter open 1/100 of a second, regardless of whether you're capturing video at 30 fps, 60 fps, or even 10 fps. If the shutter speed is 1/100 of a second, then the amount of blurring in each frame will be the same, regardless of how many frames you capture per second. You will, however, have a 'choppier' video at the slower fps numbers, even though the blurring in each frame will not be changed.
However, in practice, it's a moot distinction. The shutter speed is proportional to fps, so if you have more fps, the shutter speed will almost always be shorter and you will therefore have less blurring.

That's a huge difference, not to mention the codec advancement over MPEG-2 in DVD. Then you add on the various types and sizes of displays used for TVs and you see a much faster and more profound trend over the 50-60 years of terrestrial broadcasts on a CRT TV.
Way to ignore my question.
No one is denying that there are more pixies in BRD and that there will be more pixels with UHD or whatever comes after that. My point was that the differences to the viewer become smaller with each increment. S-VHS was noticeably better than broadcast TV from the 60s and 70s. DVD was noticeably better than S-VHS, but the difference wasn't quite as obvious. BRD is better than DVD, but again, the difference becomes less obvious. At some point, the differences will be invisible to the viewer. Even before that, the differences will become insignificant to the viewer.
It appears to me that we're very close to that line, maybe even already past it. To me, with a 60" 1080p TV at about 10 feet, the differences between BRD and DVD are subtle and hardly noticeable if you're simply watching the movie rather than intentionally looking for differences. Given the progressions, it seems to me that increasing the resolution further wouldn't even be noticeable to most people (with a very tiny number who view a 120" display under ideal conditions being the exception).
