, Strengthen Facebook Integration and launched site-wide integrations of Facebook and new social plug-ins allowing users to recommend, share, or comment on content with friends on the social-networking site, as well as to see content their friends have recommended, shared, or commented on.

New tools announced by the cable news network include: a homepage activity feed on the right side of that will combine actions of both users and Facebook friends, depending on user preference; a profile page activity module, providing similar access to friends’ activity; the ability to recommend story pages, videos, blog posts, and iReports; and NewsPulse, a filtering tool that allows users to search the most popular articles and videos by topic or keyword, as well as to consume that content without leaving the NewsPulse experience, with content sortable by popularity, number of comments, time published, and, now, number of times recommended or shared through Facebook. senior vice president and general manager K.C. Estenson said:

Today, it’s possible that people may be more connected with their friends on Facebook than they are to the people they see every day, and sharing what interests you most with your friends online has become a form of cultural currency. As one of the most trusted sources of original reporting, CNN is uniquely positioned to reinforce the connections between Facebook friends. We hope this effort will make our brand even more personally relevant to our audience.
