"In regard to propaganda the early advocates of universal literacy and a free press envisaged only two possibilities: the propaganda might be true, or it might be false. They did not foresee what in fact has happened, above all in our Western capitalist democracies -- the development of a vast mass communications industry, concerned in the main neither with the true nor the false, but with the unreal, the more or less totally irrelevant.
In a word, they failed to take into account man's almost infinite appetite for distractions."

It was Juvenal that coined this system, a mechanism of influential power over the Roman mass. "Panem et Circensus", literally "bread and circuses", was the formula for the well-being of the population, and thus a political strategy. This formula offered a variety of pleasures such as: the distribution of food, public baths, gladiators, exotic animals, chariot races, sports competition, and theater representation. It was an efficient instrument in the hands of the Emperors to keep the population peaceful, and at the same time giving them the opportunity to voice themselves in these places of performance.
