"Old Hollywood" refers to the film industry during its golden age, primarily from the 1920s to the 1960s. This era is characterized by the rise of major studios like Metro-Goldwyn-Mayer and Paramount Pictures, which produced iconic films and launched the careers of legendary stars such as Marilyn Monroe and Humphrey Bogart. The introduction of sound in films, known as the "talkies," revolutionized cinema and attracted larger audiences. The glamour and style of Old Hollywood are often associated with lavish premieres, red carpet events, and the creation of timeless classics. This period also saw the establishment of the Hollywood studio system, where actors were often under long-term contracts. The influence of Old Hollywood continues to shape modern filmmaking and popular culture today.
