Who and how did the standard of 1080p begin.

Why is 1080x1920 the standard for FULL HD? What is so special about that particular resolution?
 
Find a friend who has iphone, or if you have one will do. Take a big photo, and put it in a simple webpage, set at witdth and height half of the original.

if you have an 1200 x 800 picture, put it in the page and make it half. like this:

<img src="source.jpg" style="width:600px; height:400px" />

Put the photo in some image editor, resize it 600px x 400 px.

Put this image also in the webpage, just near the one above.
They should look as having the same size.
Look at that page with a iphone.
Be amazed.

Because it has more pixels than 480p? Therefore, a more detailed image.

Also, when LCDs came out they were native to higher than 480p resolutions which is why 480p started to look really blocky on LCDs. Where as if you look at 480p on a good old CRT it doesnt look as bad because older TVs were native to 480p.

Its not really that there is anything "special" about it. Its just the new HD standard. Soon its supposed to increase to 4000p or something from what I hear. More pixels, more detail.

I have noticed this in an Apple store while trying out the new retina Mac Book. Standard raster graphics such as pictures and images tend to render quite blury which is very inconvenient compared to regular screens.

Using images twice in size compared to its resize value will certainly take care of the retina display blur problem however it will not be as "website friendly"

First you will have to use images that are twice as big in terms of physical space hence the website will take twice as much time to load. Then in case of older browsers (which is still majority) the rendering engines render in best quality images unresized in their native size. If you render an image that is shrunk to half the old rendering engine might create strange artifacts or flaws in those images.

As a website developer I gotta say that retina displays made our days slightly harder again.
 
Its just a display standard that everyone has adopted. Though at larger screen sizes 1080 looks rather poor imo. Not enough Dots Per Inch for screens larger than 24 inches.
