The 1920s marked a significant transformation in the movie industry with the advent of sound in film, culminating in the release of "The Jazz Singer" in 1927, the first successful "talkie." This technological innovation revolutionized storytelling and audience engagement, leading to a decline in silent films. Additionally, the decade saw the establishment of Hollywood as the epicenter of film production, with major studios solidifying their influence and the rise of star culture. Overall, the combination of sound technology and the Hollywood system fundamentally reshaped the film industry.

In the formative years of the American movie industry, film-makers worked in such unlikely places as Fort Lee, New Jersey (and sometimes Havana, Cuba). But by the early 1920s, movie-making was almost entirely based in Hollywood, California. Major companies such as Warner Brothers (1923) and MGM (1924) were founded in Hollywood, and a number of elaborate and ornate new theaters were built in and around nearby Los Angeles, to support the growing film industry.
The 1920s were a great decade for entertainment firsts. Some of the most important were: Commercial radio made its debut in Pittsburgh (KDKA), Detroit (8MK) and Greater Boston (1XE, Medford Hillside) in 1920. The first broadcast of a world's series baseball game occurred in 1921. The first national radio network, the National Broadcasting Company (NBC) debuted in 1926. And the first successful talking picture, a movie called "The Jazz Singer," debuted in 1927.
There wasn't any tv in the 1920s. The first public demonstration was in the 1920s, though, so you can search "first tv ever".
In the 1920s, loggers worked in challenging conditions, often in remote forests where they faced harsh weather and rugged terrain. The logging industry was booming during this time, fueled by the post-World War I construction demand. Loggers typically used hand tools, like axes and saws, before the introduction of mechanized equipment, which began to change the industry. Safety standards were minimal, leading to high injury rates, and the work was physically demanding, requiring strength and endurance.
