First radio stations emerge


Two stations claim to be the first broadcasters: WWJ in Detroit and KDKA in East Pittsburgh. However, they both began broadcasting within months of each other, with KDKA being the most famous for its coverage of the 1920 election results. Their founding represents a shift from amateur radio operators to stations with consistent programming.
