Radio jockeys, or RJs, have been a staple of the radio industry since the early days of broadcasting. In the 1920s, American radio stations began to hire announcers to introduce songs and read commercials. These announcers became known for their smooth voices and easygoing demeanor, and they quickly became popular with listeners. Over time, announcers began to add their own personality to their broadcasts, becoming known as “disc jockeys.” DJs would often play music that they personally enjoyed, and they would sometimes talk between songs to give listeners a sense of who they were. By the 1950s, DJs had become stars in their own right, with some even achieving national fame. Today, radio is still one of the most popular forms of entertainment, and DJs continue to play an important role in keeping listeners tuned in.
