Jean Baudrillard (1929-2007) was a French sociologist, philosopher, and cultural theorist. Known for his analysis of postmodernism and consumer society, his theories focused on the concepts of simulacrum, hyperreality, and the implosion of reality in the era of mass media. He was an influential figure in post-structuralist and postmodern thought, criticizing modernity, technology, and the way signs and symbols replace reality itself. Among his most notable works are "The System of Objects," "The Consumer Society," "Simulacra and Simulation," and "America."
