Hidden video cameras are now used in most stores and in many other places, computers are used to collect and process vast amounts of information about individuals. Information so obtained greatly increases the effectiveness of physical coercion (i.e., law enforcement). Then there are the methods of propaganda, for which the mass communication media provide effective vehicles. Efflcient techniques have been developed for winning elections, selling products, influencing public opinion.
