Film title design is a term describing the craft and design of motion picture title sequences. Since the beginning of the film form, it has been an essential part of any motion picture. Originally a motionless piece of artwork called title art, it slowly evolved into an art form of its own.
In early film, main title design consisted of the movie studio’s name and/or logo and the presentation of the main characters along with the actor’s names, generally using that same artwork presented on title cards. Most independent or major studio had their own title art logo used as the background for their screen credits and they used it almost exclusively on every movie that they produced.
Then, early in the 1930s, the more progressive motion picture studios started to change their approach in presenting their screen credits. The major studios took on the challenge of improving the way they introduced their movies. They made the decision to present a more complete list of credits to go with a higher quality of artwork to be used in their screen credits. Read more at Wikipedia.
