Social media is impacting journalism in several ways. It is changing how news is managed and distributed, as content management systems make it easier to share stories across platforms like Facebook and Twitter. Journalists are encouraged to engage audiences on social media by sharing links as well as rich media like photos and videos. Nearly half of Facebook users get news through the site. Citizen journalism through user-generated content submitted on social media is also impacting the industry. While social media helps distribute news, search engine optimization remains important. As journalism evolves, the majority of Americans still get news from print or online sources, though mobile-only readers are increasing.
