The 4:3 Aspect Ratio is commonly known as the fullscreen aspect ratio. The 4x3 (1.33:1) format became the first standard ratio for televisions and computer monitors as it was easy to use due to the camera formats.

Back in the days, there was plenty of video and movies recorded in the 4:3 aspect ratio, so they didn't need to be converted for the TV release.

It was first later in the 1990s and 2000s the widescreen 16:9 ratio became more popular as a video ratio format.
