Opening theme

A title sequence (also called an opening sequence or intro) is the method by which films or television programs present their title, key production and cast members, utilizing conceptual visuals and sound. It typically includes (or begins) the text of the opening credits, and helps establish the setting and tone of the program. It may consist of live action, animation, music, still images, and/or graphics.

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.

Slowly, title sequences evolved to become more elaborate pieces of film. The advent of television was a pivotal moment for title design because it forced the major film studios to invest in making cinema more attractive in order to win back a diminishing audience. The "cast of thousands" epics shot on various patent widescreen formats were a direct response to television's successful invasion of the leisure marketplace. Part of cinema's new prestigious and expansive quality were orchestral overtures before the curtains opened and long title sequences — all designed to convey a sense of gravitas it was hoped television would be unable to compete with. As cinema's title sequences grew longer and more elaborate, the involvement of graphic design luminaries such as Saul Bass and Maurice Binder became more common. The title sequence for Alfred Hitchcock's North by Northwest is generally cited as the first to feature extended use of kinetic typography. This innovation, in turn, influenced the 1960s television predilection for title design, resulting in the creation of strong graphics-led sequences for many television shows. Since then, the mediums of film and television have engaged in a kind of push and pull behavior, inspiring and spurring each other in different directions.
