The active use of the Internet in Korea has contributed substantially to the establishment of democracy. The parliamentary election of 2000 was the prelude. For the first time, homepages were used on a massive scale in the election campaign, admittedly still without much success. More effective were the websites of the civil organizations which took up positions for and, above all, against candidates: the “rejection movement” was able for the first time in the political history of Korea by means of the Internet to determine election campaign themes from the grassroots and then to introduce them to the public so effectively that it decided the election. During the presidential election of 2002 the Internet was used particularly effectively by the supporter groups of the candidate (and later victor) Roh Moo Huyn. Beyond influences on the election result the special feature of the 2002 presidential election was that the citizens were no longer merely passive voters but rather participated actively in the processes of political opinion forming. In this the Internet had an important role, particularly as the forum of a public counter-discourse with which the media monopoly of the big conservative newspapers could be broken. The third phase of the “Internet revolution” began in 2004 with the protest movement against the removal from office of President Roh Moo Huyn pursued by the opposition. In this phase the netizens detached themselves from the established organizations and became much more politically active in order to strengthen the hitherto fragile democracy. The Internet as a forum of alternative political discourse developed qualitatively, and at the same time the online activities were complemented by offline actions involving up to 200,000 participants. Korean politics has become more transparent due to the extension of e-politics. With the Internet citizens have found the decisive means with which to overcome the one-sided support given to the conservative camp by the newspapers, which are controlled by a handful of families. The one-sidedness of the print media has been a major hindrance to democratic development in Korea since 1987. Now the citizens as netizens can actively participate in political debate, form an online public, and by that means also exert influence on the offline public.
