Background: Beginning around 1993-94, movies originally produced and/or exhibitedin widescreen, when shown on television and home video, were preceded by a message explaining that the films' original aspect ratios were modified to fit onto the 4:3 ratio of TV sets of the era. These days, with the mainstream popularity of widescreen TVs and current home media almost always presenting films in their original ratios, these messages have fallen out of favor, though they are sometimes used on TV when films wider than the 16:9 ratio are formatted to fit it.
