"The information revolution reinforced the spread of democracy because it permitted people to inform themselves and react to what they learned more quickly than in the past. It became more difficult during the Cold War to withhold news about what was going on in the rest of the world, as well as to conceal what was happening within one's own country. This kind of "transparency" provided new kinds of leverage against authoritarian regimes, as the Helsinki process dramatically illustrated. It also brought assurance, where dictatorships had been overthrown, that they would not return."
