Some Interseting Geek Speak

i forget where i came across this but the source is credited as best i can at the bottom of the article.

Essentially all sound films (up to 1953) were at an aspect ratio of 1.37:1 (aka "The Academy Standard Ratio.") Prior to the advent of sound, the ratio was slightly less (1.33:1). This ratio, also known as 4:3, is today's common TV ratio.
So where did 2.35:1 originate? With the television boom in the early 50's, the film industry experienced a drastic decline in ticket sales. With many previous Hollywood productions easily adapting into the 4:3 TV format, the public was staying at home to watch movies. In order to get people out of their living rooms and back into the theaters, 20th Century Fox developed a new "supersized" format which audiences couldn't experience on the "small screen."

This invention was the CinemaScope image which was photographed on a standard 35mm film with an Anamorphic Lens. When the image was projected in the theather, through another anamorphic lens, it produced an aspect ratio of 2.35:1 which was two and a half times the size of the conventional TV screen.

Developed by Professor Henri Chretien, 20th Century Fox released the first "CinemaScope" film (The Robe) in September 1953. Since its introduction, variations of the "widescreen" format have been introduced - noted by the modification on the "scope" term; coined by film companies from all corners of the globe.

Below, is a listing of the various spin-off "scope" formats. All formats are in 2.35:1 unless otherwise noted.
NOTE - Not many spot the difference (outside of projectionists and film technicians) but the ratio was enlarged by .05 back in the seventies. While the correct ratio is 2.4:1 (even 2.39:1), the "old 2.35:1" seems to have just stuck.
