"Hollywood Milestones" refers to significant events and achievements in the film industry that have shaped its history. Key milestones include the establishment of the first studio system in the 1920s, the introduction of sound in films with The Jazz Singer in 1927, and the rise of blockbuster films in the late 20th century, exemplified by Star Wars in 1977. These milestones not only mark technological advancements but also reflect changes in audience preferences and cultural trends. The creation of the Academy Awards in 1929 and the emergence of independent films in the 1990s further illustrate Hollywood's evolving landscape and its impact on global cinema.
