Neil Postman, in his book "Amusing Ourselves to Death: Public Discourse in the Age of Show Business," explores the evolution of communication and its impact on society’s conception of truth. He argues that as cultures transition through various forms of communication—from oral traditions to writing, and then to printing and television—there is a corresponding shift in how people understand and perceive truth. Each medium alters the way information is processed and shared, influencing public discourse.

This transformation highlights that the medium through which ideas are conveyed plays a crucial role in shaping societal perspectives. Postman warns that television, as a dominant medium, prioritizes entertainment over substantive discourse, leading to a trivialization of important discussions. Consequently, the way truth is defined and communicated evolves alongside these cultural shifts, affecting everything from politics to public opinion.
