Michel Foucault analyzed the relationships between power, knowledge, and the formation of subjectivity. He examined how power operates through surveillance and control of bodies, such as in Bentham's Panopticon design for prisons. Foucault also studied the use of surveillance and control of information in various political contexts like military camps, Nazi Germany, and modern media and celebrity culture. His theories influenced authors like George Orwell who depicted total state control of information and surveillance in novels like 1984.
