Serial fiction about wireless and radio was the most popular young adult literature at the turn of the 20th century and a form of early social media. Before television and the Internet, book about plucky youths braving danger and adventure with the help of wireless communication brought young people together. They gathered in basements to build crystal sets and listen to early broadcasts. They built transmitters and talked to each other across neighborhoods, cities and states. By 1920, there was music on the airwaves and boys and girls tuned in on homemade radios, inspired by their favorite stories.
