This study aims to determine the influence of comments posted online about news on viewers. Opinions posted by news readers via the web often influence the formation of other readers’ views. In this paper, we investigate the impressions of news articles under three conditions: (a) presenting a news article only, (b) presenting a news article and comments posted in the comment section of the article by readers, and (c) presenting a news article, comments posted by readers, and the readers’ previous comments for other news articles. The result revealed that (1) readers’ comments do not affect the impression of the original news article but are more influenced by the perspective of whether the respondent is familiar with the news article, (2) The impression of the comments that viewers agreed on tend to emphasize sincerity, responsibility, and credibility, regardless of the news article’s genre, and (3) presenting readers’ past comments may influence viewers’ evaluation of the information and lead them to form different opinions.
