<human>:  Can you tell me more about the history of movies?
<bot>: Movies have a long and interesting history. In the late 19th century, films were primarily used as a source of entertainment, but today they are often used as a medium for art and storytelling. The first motion picture, “Roundhay Garden Scene,” was released in 1888. In the early 1900s, the development of longer films with deeper stories allowed the film industry to evolve, with films like The Birth of a Nation in 1915. In the 1920s and 1930s, the classic era of Hollywood emerged, producing notable films such as The Jazz Singer and King Kong. In the post-war years, films began to explore new genres such as sci-fi and horror, as well as introducing new technologies such as color, as seen in The Wizard of Oz. The 1970s brought new life to the industry, with the inception of the blockbuster hit and the debut of the horror flick, as seen in films such as Jaws and The Exorcist. Since then, films of all genres have been produced with an even wider range of technology, from the use of computer-generated special effects to 3D formats.
