The explosion of the Covid-19 pandemic has led to a major transformation in media consumption and the use of social networks. New habits and extensive exposure to connected devices coupled with unmanageable amounts of information warn of a worrying reality, especially among the younger population. The aim of this research is to discover the degree of trustworthiness of Generation Z towards the media, their media consumption preferences and the association they make between media consumption and fake news. Using a descriptive and exploratory quantitative methodology, a study is presented with a sample of 225 young people belonging to this population niche. The study addresses three dimensions: media consumption, social networks and perception of fake news. The results show that generation Z is an intensive consumer of the media they trust the least and perceive traditional media as the most trustworthy. The findings indicate that social networks are the main source of information consumption for this ge­neration, among other content, despite also being the least trustworthy and the most likely to distribute fake news according to their perceptions. There is a lack of media literacy from a critical rather than a formative perspective.
