This paper aims to examine whether generation differences exist in media effects on acquiring important political issues. The results showed that there were no significant differences in important issues among the youngest, baby boomers, and the civic generations. However, there were differences in effects of media use, media reliance, and media credibility on political issues recognition. Internet obviously plays an important role in the youngest generation. Using data from Taiwan Social Change Survey (TSCS) based in Academia Sinica, our analyses showed that time spent on Internet news in the youngest generation served as a better predictor than time spent on TV news and newspaper news. Although time spent on Internet news, reliance on Internet news, and Internet news credibility did not predict any political issues cognition in the other two generations, the extent of reliance on newspaper news and TV news credibility predicted political issues recognition to certain degree.
