摘要：

Gatekeepers usually control news information. However, recent technological advancements might require rethinking previous gatekeeping hierarchies. Aggregation algorithms currently filter and present news information to millions of American Internet users daily. A content analysis demonstrates significant differences between health news content retrieved from Web sites that aggregate their articles from many sources (e. g., Google News), and those that focus on providing news from a limited number of sources (e. g., CNN.com). Explanations for these content differences are discussed, as are implications concerning health information seeking and Internet news consumption.
