The success of news aggregators has generated a heated debate about whether news aggregators steal traffic from newspapers or increase traffic to newspapers. This survey article provides an overview of recent articles on news aggregators. After providing a simple theoretical framework, I first review empirical articles and then theoretical ones. While the empirical articles try to assess the effects on traffic to newspapers, the theoretical ones go beyond and try to analyze the e¤ects on newspapers'incentive to invest in quality journalism. I conclude by raising some questions for future research.
