The practice of roadshow presentation began dying out in the 1970s, partly due to a string of costly box-office flops, and partly due to the rise of the multiplex. As multiplexes began to increase in number, and as more and more skyscraper hotels and office buildings took the place of the oldtime movie palaces, theater exhibitors began showing long films in a more informal format. Francis Ford Coppola's Oscar-winning epics "The Godfather" (1972) and "The Godfather Part II" (1974), for instance, were made with mono sound, shown without intermissions, and were given more than two performances a day, despite their extreme length. Stanley Kubrick's "Barry Lyndon" (1975) was shown more than twice a day, but included an intermission.
