The War of the Worlds is an unconventional radio show that forever changed the world of mass communication and allowed the entire nation to see the power of imagination and unique power of the radio on its audience. The creators of this national hysteria were Orson Welles and the Mercury group. Orson Welles was a famous American actor, producer, director, and radio host. In an effort to increase the show's audience, Orson Wells implemented the idea of ​​a public Halloween scare. The War of the Worlds radio show was a dramatization of H.G. Well's novel The War of the Worlds (1898 novel telling the story of an alien invasion on Earth) and was featured as a scary Halloween episode on the Mercury Theater On radio show The Air. The episode aired on the Columbia Broadcasting System (CBS) on October 30, 1938. The first two-thirds of the 62-minute broadcast were presented as a series of simulated news broadcasts, which suggested to many listeners that a real alien invasion by Martians was currently underway. The act scripted by Orson Welles was so convincing that the broadcast caused hysteria across the nation as several listeners believed that the nation had actually been invaded by Martians in a seemingly unstoppable attack. Many people were terrified by the news and left their homes in panic and fled. The consequences of the broadcast were so disastrous that even Welles and his team were shocked. This 62-minute broadcast in 1938 truly changed the meaning of mass media and everyone came to realize the true potential and power of mass communication. Orson Welles and his team had written the screenplay for their radio comedy The War of the Worlds, taking inspiration from author HG Well's novel The War of the Worlds (1898 novel which tells the story... half of the sheet of paper... ) and allowed them to see how the media can be manipulative. Analyzing the results of this media, we can say that the World Cup radio broadcast war had revolutionized mass communication and started a new era in which the media was forced to focus on public demand. In the days following the adaptation, however, there was widespread media outrage over the cruelly misleading news format from newspapers (who lost their revenue to the new radio programs) and public figures, prompting an outcry against broadcasters and requests for regulation by the Federal Communications Commission. Overall, listening to this old radio show made me realize how dangerous one-way communication can be, so if today's media wants to succeed, they should try to be non-manipulative and honest with the public.
