Since 1950 onwards, a new aspect ratio emerged that is 16:9 also known as wide screen.
In the 50s’, TV became immensely popular and filmmakers needed a way to get people back into movie theatres.
By using an aspect ratio where the width is twice the height, they created a new cinematic experience. When an image extends to fill more of your peripheral vision, what you watch is more engaging. That is why this ratio is widely used for film with the view of mountains, ocean, forest, desert etc.
16:9 became an international HDTV format, where, 16 refers to the screen width and 9 is the height. Today, 16:9 or wide screen is the commonly used aspect ratio across computers, TV and Internet videos.
