How did we adopt standard rendering settings such as 1080p resolution, 30-60 fps, 60-144 hz refresh rate, etc.?

I'm curious as to how we came up with these standard values that most screen manufacturers, game creators, video rendering programs have adopted, etc. have adopted.

The standard TV refresh rates - 50Hz in former "PAL" countries, 60Hz in former "NTSC" countries - came about largely because they matched the frequency of the alternating current used in the countries that developed them, although NTSC later screwed this up and has annoyed a generation of broadcast engineers by dropping it to 59.94Hz when they introduced colour.
