The newspaper is a printed daily or weekly bulletin used to inform the public. Changes in field of technology caused that print media also reach their readers through the virtual world. The aim of the research was to get a general overview of pseudonyms in Slovene printed journals and their portals. For research we used the content analysis method. In the sample we included 3 Slovenian newspapers Dnevnik, Delo and Večer in three periods of publication, namely 4 months a year. In the portals Delo, Večer and Žurnal24, we focused on the commentators. We studied under what kind of pseudonyms they publish their comments and if the pseudonyms express any attributes of "showy and aggression" and "sweetness and pleasantness". We collected 75 pseudonyms into the sample. In the last 70 years, the trend of publishing articles has changed. Initially, they hid their identity without signing the article. In 1991, a growing number of articles were signed with the name and surname. Today we still find signed articles with the initials of the names, and also articles that are signed with the author's name and last name. The most frequent initials of the name appear 2,7 times more than the most frequent name. Users in the online environment mostly hide their identity with a pseudonym. Pseudonyms on portals indicate weak "sweetness and pleasantness" and weak "showy and aggression". The newspapers portals follow a model that requires the listing of personal data, but they are not published and also the model where they can completely hide their identity. Pilot survey is a step forward in the field of investigating pseudonyms in newspapers and newspaper portals in Slovenia.
