Citizen Kane is often considered one of the greatest films of all time, but it's subjective and there are many other great films too. The Golden Age of Hollywood brought many innovations to the film industry, such as sound and color, and established Hollywood as the center of the film industry. These practices still thrive today, with Hollywood continuing to produce blockbuster films that are enjoyed around the world. Social, economic, and political factors have all affected Hollywood and its cultural production. For example, the Hays Code, which was a set of guidelines for film content, was established in response to concerns about the moral impact of films. Additionally, Hollywood has been affected by changing economic conditions, such as the rise of streaming services and changes in how films are distributed. Political factors have also played a role, with Hollywood often reflecting and influencing cultural and political trends.
