Jean Baudrillard was a French philosopher who lived from 1929 to 2007. He wrote about a lot of different topics, but he was most famous for his ideas about how we make sense of the world around us. He said that our understanding of reality is shaped by the images, symbols, and messages that appear in our everyday lives, like on TV and in newspapers. He said that these images and messages have become so powerful that they have become more "real" than reality itself. So, for Jean Baudrillard, the things we see and hear on TV, in magazines, or on the internet can be more important and powerful than the real things around us.
