  During the late 1960s, Baudrillard published a series of books that would eventually make him world famous. Influenced by Lefebvre, Barthes, and a series of French thinkers whose influence will be discussed below, Baudrillard undertook serious work in the field of social theory, semiology, and psychoanalysis in the 1960s and published his first book The System of Objects in 1968 (1996), followed by a book on The Consumer Society in 1970 (1998), and For a Critique of the Political Economy of the Sign in 1972  (1981).[2] These early publications are attempts, within the framework of critical sociology, to combine the studies of everyday life initiated by Lefebvre (1971 and 1991 [1947]) with a social semiology that studies the life of signs in social life. This project, influenced by Barthes (1967 [1964], 1972 [1958], and 1983 [1967]), centers on the system of objects in the consumer society (the focus of his first two books), and the interface between political economy and semiotics (the nucleus of his third  book).[3] Baudrillard’s early work was one of the first to appropriate semiology to analyze how objects are encoded with a system of signs and meanings that constitute contemporary media and consumer societies. Combining semiological studies, Marxian political economy, and sociology of the consumer society, Baudrillard began his life-long task of exploring the system of objects and signs which forms our everyday life.
