Harold D. Laswell

Harold D. Laswell was a prominent American political scientist and communication theorist best known for his work on how media and communication influence society. He developed a framework called the "Who- Says- What- In which channel- To whom- With what effect" model, which helps analyze the process of communication. Laswell's ideas emphasize understanding the roles of the communicator, message, medium, audience, and outcomes in shaping public opinion and political processes. His work remains foundational in fields like communication studies, political science, and media analysis, providing a systematic way to study how information impacts society.
