Why are old movies and videos are in a square frame and nowadays they are in a rectangle frame?
In: Technology
* Cinema was 4:3
* TV came along at 4:3
* Cinema went wide-screen as a way to differentiate itself from TV. (2.35:1 became common).
* TV developed a mid-way windscreen 16:9 format
Cinema started before tv and used a squarish 4:3 aspect ratio.
TV came along, also using 4:3. Cinema developed various wide-screen formats as a way to attract more people away from TV and back to the cinema.
TV made standards and decided to go for wide-screen 16:9 as a half way between squarish TV and the much wider common cinema format.
Around this time, TV went through a technological shift from CRT to LCD as well as from analog to digital broadcast and it meant people upgrading were only choosing wide-screen TVs
