Until the 1950s, the dominant mass medium was the newspaper. While the telegraph and personal letters were important means of communication, they were not as widely used as newspapers, which were a primary source of information and entertainment for many people. The radio did gain popularity in the early 20th century, but it was not until the 1950s that television became the dominant mass medium.
