What was the last American movie to air in black-and-white for non-artistic reasons?

Movies used to be in black and white. Now they're in color. When did this happen, and what was the last movie to be in black-and-white for non-artistic reasons? (Like, Schindler's List was in black-and-white, but that was an artistic choice.)What was the last American movie to air in black-and-white for non-artistic reasons?Not sure which was the last, but "A Hard Day's Night" and "Night of the Living Dead" were both shot in black and white for reasons of expense.

EDIT: I also would like to point out that colour filming was available in the 1930's but a bulk of films were made in black and white due to reasons of expense and only when colour filming became more economically feasible did films begin to be made in colour. Many of Alfred Hitchcock's films are in black and white but many are in colour. "Psycho" was made in black and white, colour was readily available, "North by Northwest" (an earlier film) was made in colour. Alf may have WANTED "Psycho" in B/W due to the lack of adequate special effects at the time, or perhaps it was done for reasons of expense due to its basically being a slasher film and thought possibly it might not be as profitable as it was. "A Hard Day's Night" was shot in B/W due to the fact that the studio was sure they could recoup the expense if money was saved on the filming. And, of course, practically anything made for television in the 1950's was made in B/W due to the fact that no one could see the point of filming in colour to be viewed on a B/W medium. I'm uncertain as to the assertion that "Clerks" was shot in B/W due to budget reasons, because I read an article years ago that stated that shooting in B/W is actually MORE expensive than shooting in colour due to not having B/W film, as it's not manufactured much due to its lack of demand.What was the last American movie to air in black-and-white for non-artistic reasons?You can't really draw a line on the last black and white film, but the switch from mainly black and white to mainly color probably happened through the 60s. 50s movies are generally black and white, 70s are generally color.What was the last American movie to air in black-and-white for non-artistic reasons?I know that Clerks was made in black %26amp; white partially for budget reasons. That was 1994.What was the last American movie to air in black-and-white for non-artistic reasons?
