Baudrillard defined "hyperreality" as "the generation by models of a real without origin or reality"; and his earlier book Symbolic Exchange and Death. Hyperreality is a representation, a sign, without an original referent. According to Baudrillard, the commodities in this theoretical state do not have use-value as defined by Karl Marx but can be understood as signs as defined by Ferdinand de Saussure. He believes hyperreality goes further than confusing or blending the 'real' with the symbol which represents it; it involves creating a symbol or set of signifiers which represent something that does not actually exist, like Santa Claus
