U radu se obrađuje praćenje predizborne kampanje prvih slobodnih izbora u Hrvatskoj u hrvatskom tisku. Autor je nastojao utvrditi je li postojala medijska pristranost u praćenju predizborne kampanje prvoga kruga parlamentarnih izbora 1990. u Hrvatskoj. Analizirano je na koji su način dnevnici (Vjesnik i Večernji list) i tjednici (Danas i ST) pisali o političkim strankama i koalicijama u promatranom razdoblju. Prvi cilj istraživanja bio je dokazati postoji li medijska pristranost, a drugi postoji li pluralizam medija nakon gotovo polustoljetnoga jednostranačkoga socijalističkog sustava. Pokazalo se da medijska pristranost postoji u svim promatranim medijima, ali se favorizirane i marginalizirane stranke razlikuju ovisno o promatranome mediju. The paper deals with the coverage of the election campaign of the first free parliamentary elections in Croatia in the Croatian press. The aim is to establish whether media bias existed in the coverage of the election campaign of the first round of the parliamentary elections in 1990. It analyses how the dailies Vjesnik Herald and Večernji list Evening Paper and weeklies Danas Today and ST covered the political parties and coalitions in the examined period. Three subdivisions of media bias are defined: gatekeeping bias, which is a tendency of the media to give a disproportionate amount of space to the election favourites; content bias, which exists if the relevant options are not given an equal amount of space; and statement bias, which exists if some relevant parties are portrayed in a more favourable way than the others. The first aim of the research is to demonstrate whether media bias existed in the coverage of the election campaign, and the second to determine whether media pluralism existed after almost half a century of a one-party socialist system. Quantitative content analysis is used to analyse a total of 1,185 articles included in the research. It is shown that media bias existed in all analysed media, but the favoured and marginalised parties were different.
