<bot>: The movie industry has changed and developed dramatically over the last century. From silent films that ran for only a few minutes to the introduction of sound, color, and widescreen films, the cinema has come a long way. Special effects, computer-generated images (CGI), 3D, and even virtual reality have transformed the way movies are presented and experienced. Movie theaters, once simple structures often filled with uncomfortable benches and no concession stands, have now become luxurious multi-screen complexes with digital projection systems, gourmet snacks, and giant screens. Additionally, with the advent of streaming services and digital platforms, films can now be watched almost anywhere at any time, adding even more convenience and flexibility to the movie-going experience.
