resolutions and aspect ratio of video formats and screens

There are quite a few of video formats (standards) that more or less make no sense, here are few examples:

240p, 360p, VGA, NTSC DV, NTSC D1, PAL, 1k Academy, HDTV 720p, HDTV 1080, 2K Academy, 4K Academy

I created a spreadsheet to keep track of the variety.. 

See updated spreadsheet here (access permission needed).

Bottom line is that we now the standard is 1080p and the new standard will be 4K.
