Abstract: A Cohort based content filtering and display system and method that enable users to obtain near-real-time information about how specific groups of users react to news, products, people, or other items. The system will aggregate and display commercially valuable, near-real-time information about user preferences and attitudes, sorted according to standard demographic and other user categories employed by marketers, research organizations and others, without compromising individual privacy. In some embodiments, a user can select a Cohort of interest to him or her, and then see what is most relevant to that Cohort, even if this user is not a member of the selected Cohort.
