Define and explain French sociologist Jean Baudrillard's "simulacrum" concept.

All answers should be able to explain that this concept is an attempt to understand the emergence of postmodern society. Jean Baudrillard argued that people were losing the ability to distinguish between what is real and what is fake, especially when media representations were involved, and that we would also come to accept the fake as sufficient and therefore no longer even need the real. He called this new socially constructed reality the "simulacrum," or a simulation that becomes as good as real. The problem with the simulacrum is that the eye can be tricked and images can be manipulated in order to give the illusion of reality. Following Baudrillard's logic, "the image has come to replace the real" for people in a postmodern, media-driven society.
