The study analyzed over 1,200 social media posts from six major news organizations on Facebook and Twitter over a one-week period. It found that news organizations posted more frequently on Twitter than Facebook, except for CNN. Facebook posts contained more evergreen, lifestyle, and soft news stories written by staff, while Twitter featured more spot news, disasters, politics, and hard news from wire services and links. Posts on the two platforms also differed in their geographic focus, with Twitter prioritizing more international stories and Facebook having more posts without a clear location. The findings suggest journalists act as gatekeepers by distributing different types of information on each social media site, which could influence audience perceptions.
