The first opening sequence was in the film "Intolerance" in 1916. They traditionally only acted to show the people who were involved in the making of the movie e.g. Director, producer etc.
But as the film industry evolved they started include themes into the sequences which were related to the film for example Se7en where it shows a mad man cutting his fingers etc.
Recent films now do not even have opening credits at all and throw us straight into the action like in The Dark Knight which goes straight into a bank heist. Another technique which is popular among fantasy is the use of text to set the scene of the movie which will either be in an alternate world, the past or the future e.g. Gladiator, Star Wars, Hunger Games.
