Hypodermic Needle Theory, also known as Magic Bullet Theory (hypodermic syringe model or transmission-belt model) was promulgated by Harold Lasswell in 1920s.

The hypodermic syringe model believes that the media can have a direct and immediate effect on the audience. This model sees the audience as a ‘homogeneous mass’ (all the same), as passive and believing what they see in the media without questioning the content.When was the Hypodermic Needle Theory invented?

How does a hypodermic needle model work?
