The Invention of the Radio
Up until the 1920's, radio barely existed. Thanks to Frank Conrad in 1920, Americans were now able to enjoy this new technology. Conrad, who worked for the Westinghouse Electric Company, set up a radio transmitter in his garage in Pittsburgh and sent recorded music over the radio. With a successful experiment under his belt, Westinghouse began broadcasting and soon became the nations first radio station, known as Pittsburgh's KDKA.
Movies
Ever since their invention motion pictures had been instantly popular. During the 1920's audiences grew and popularity continued to rise. Although, there was one flaw: the movies did not have sound. In 1927, the first successful sound film, The Jazz Singer, changed the movie industry. More theaters began to play these motion pictures accompanied by sound. This new innovation caused a continued boom in the industry.
