I wonder how many people predicted that live theater was going away when long form movies came into vogue. Or that movies in turn would fade away when TV became widespread after WWII.
Movie makers became nervous about losing out to T.V. back at the end of the 1940s, when T.V.s were still pretty rarely owned on a large scale. But what has killed off play/movie/and network T.V. has been unions and the garbage that all three things now produce/put on; self inflicted destruction; all!
