In 1907 Reginald A. Fessenden became the first to send audio (wireless telephony) by means of electromagnetic waves. By 1910 these systems had come to be referred to by the common name of "radio".
Amplifying vacuum tubes revolutionized radio receivers and transmitters. Many famous scientists, including Thomas Edison, Eugen Goldstein, Nikola Tesla, David E. Hughes and Johann Wilhelm Hittorf, experimented with Vacuum tube technology. The groundwork laid by these inventors and scientists and was critical to the development of vacuum tube technology which led to the introduction of Vacuum tube radio receivers.
