The Hypodermic Needle Theory suggests that audiences passively absorb intended messages from media like television without questioning or rejecting them. This theory was popular in the 1930s but has since been disproven. The 1938 radio adaptation of "War of the Worlds" by Orson Welles caused widespread panic, supporting the idea that audiences uncritically accept media messages. However, the theory is now seen as inadequate because audiences have preexisting opinions and are not completely shaped by media. The Payne Fund studies from 1929-1932 also contributed to this view of powerful media influence but lacked scientific rigor and methodology.
