One of the greatest examples of the power of early radio. Many who heard the original broadcast freaked out, as they were convinced the Earth was being invaded by Martians. This monumental broadcast was created by Orson Welles as part of his Mercury Theatre on the Air. It was inspired by H. G. Wells' science fiction novel The War of the Worlds. It originally aired on October 30th, 1938.
It is believed that six million people heard part or all of the live broadcast, and at least half of them either believed what they were hearing was true or were at the very least, becoming concerned. We are used to hearing/seeing “fake” news now, but to fake an entire news event on radio was unheard of back in 1938.
