In earlier days, the National Anthem was played along with the day’s news in theatres before the movie starts or at the end. Slowly it was noticed that people were busy finding their seats or finding the nearest exit and nobody was paying attention to the National Anthem. Also most of them were chatting and sitting and not giving due respect. After a while playing of the National Anthem was stopped.
Supreme Court has now asked all theatres to play the National Anthem before a movie starts with the National flag on screen. Everybody in the hall should rise and sing the anthem.
