 Their critical theoretical work peaked on the highly influential book "The Society of the Spectacle" by Guy Debord.Debord argued in 1967 that spectacular features like mass media and advertising have a central role in an advanced capitalist society, which is to show a fake reality in order to mask the real capitalist degradation of human life.To overthrow such a system, the Situationist International supported the May 1968 revolts and asked the workers to occupy the factories and to run them with direct democracy through workers' councils composed by instantly revocable delegates.
