The Columbia Journalism Review report on a study on news consumption in the Information Age which says:

Chief among the findings was that many young consumers craved more in-depth news but were unable or unwilling to get it. “The abundance of news and ubiquity of choice do not necessarily translate into a better news environment for consumers,” concluded the researchers in their final report. “Participants in this study showed signs of news fatigue; that is, they appeared debilitated by information overload and unsatisfying news experiences . . . . Ultimately news fatigue brought many of the participants to a learned helplessness response. The more overwhelmed or unsatisfied they were, the less effort they were willing to put in.”
