Since the invention of the cinematograph, simple title cards were used to begin and end silent film presentations in order to identify both the film and the production company involved, and to act as a signal to viewers that the film had started and then finished. In silent cinema, title cards or intertitles were used throughout to convey dialogue and plot, and it is in some of these early short films that we see the first examples of title sequences themselves, being quite literally a series of title cards shown at the beginning of a film. With the arrival of sound, the sequence was usually accompanied by a musical prelude or overture.
