There were two main types of radio stations in the 1920s - 'A' stations that played popular music and produced serials, and 'B' stations that focused on classical music and educational talks. New technologies also emerged, like John Logie Baird demonstrating televisual broadcasting using mechanical scanning in 1926 and Vladimir Zworykin working on the iconoscope television camera tube. Jazz music grew in popularity during the decade, especially the bandleader and singer Louis Armstrong. Dancing fads also emerged, such as the Charleston dance craze.
