Communicative power often grows exponentially at the time of revolutionary events, and finds its own channels. Before the 1789 revolution in Paris, there were around sixty newspapers throughout France. By the middle of 1792 there were around 500 in Paris alone. Many of them were short-lived, with a tiny circulation. But what is remarkable is the explosion of communication channels as well as the sheer increase in volume – newspapers and gazettes with a huge range of formats and tone; subscription journals; illustrated literature such as almanacs, copies of speeches, prints, engravings and the like. (For information on the power of the press, see Jack Censer's impressive Prelude to Power: Parisian Radical Press, 1789-91). Same happened with the English Revolution (Digger texts, explosion of pamphlets, eg Leveller texts, etc -- Christopher Hill, The World Turned Upside Down etc [and look closely at what's happening to James Naylor on the cover of Hill's text to find out how revolution silences its critics], and in the Russian Revolution -- Mayakovsky, Malevich, political posters, theatre, as well as the political press. Or the use of phones & faxes in the rising in Beijing in 1989. Communication & persuasion are central elements.
