Today I found myself referring to a 'pop video'. Yet the video format is now positively historic. What is the current correct phrase for a film that promotes a song...if even that is a correct description? Is it a 'pop DVD' now?
Video is a generic term for moving images made up of a succession of still images, it doesn't only refer to tapes, DVDs have video on them, you watch video on your TV, if you go to the cinema the film you are watching is video.
