The correct answer is A) the War of the Worlds broadcast.
The event that most changed how the radio was used to present news was the War of the Worlds broadcast.
The "War of the Worlds" broadcast changed the way the radio presented news and information because it realized the way it could impact the audience and their emotions.
As part of the radio show "The Mercury Theater on the Air," Orson Welles adapted the story "The War of the Worlds" of G. H. Wells and broadcasted it live as if it was real. The broadcast of October 30, 1938, created panic in the audience of the city because they thought that the invasion described in the show was real.
That was the way radio producers knew the impact the radio could create in audiences.
