The development of the Internet and modern tehnologies has largely impacted media which have had to change and adapt to a new tehnological enviroment and new changed way of comunication on the Internet. By using new possibilities of Internet media it came to the development of new type of journalism – Online journalism. Online journalism implies transmition of information through World Wide Web, where news are transmited and presented in a new, specific way - according to characteristics and possibilities that Internet provides. Main characteristics of online journalism which are in the same time distinctional from traditional media are interactivity, multimediality, non-linearity, connectivity, archiving, immediacy and sourceness. Method of content analysis determined content features of Internet publications of most visited Croatian online news portals and quality of journalistic interpretation of news. The content of article was firstly analyzed through established categories such as the main topic of the article, topicality, territorial orientation, depth of news interpretation, tone and value judgement, citations and autorship over content, and then through categories that are characteristic only of online media: multimedia, hypertextuality and sourceness. The topics that are most represented on Croatian portals are sports, entertainment and show business, as well as health because of the current emergency situation in the world related to the Covid-19 pandemic. The topics of culture and art, religion, economy and social issues are very little represented. The content of online publications is mostly superficially processed, without deeper analysis, and journalists very rarely make value judgments. Technological possibilities of multimedia are very poorly used while the possibility of connecting content is recognized as an important element in presenting news and Croatian online media are increasingly using hypertextuality, but still have much room for further development and progress towards exploiting all possibilities provided by the Internet.
