TV techs: why was 720 and 1080 chosen specifically?

Why were those resolutions chosen: 720 and 1080 lines of resolution? Is that in any way related to angles and/or circles?

Please post in the audio/video forum. Then, if they thread crap there, they can be vacationed accordingly. -DrPizza
 
Well, the TV's are more than likely based on the standard HD content. For HD cameras those are the two standard recording formats. link

Edit: Looks like it has to do more with squares than circles:

Although all HD video is displayed as 16x9, most formats do not actually record a true, full raster 16x9 image. There are only two square pixel, full raster 16x9 frame sizes:


1920x1080
1280x720
