The 2011 Tunisian and Egyptian revolutions saw significant use of Twitter for information dissemination. Researchers analyzed Twitter data from two periods—Tunisia (Jan 12–19, 2011) and Egypt (Jan 24–29, 2011)—to understand how information flowed among users, including journalists, bloggers, activists, and mainstream media. They identified patterns of information sharing and the roles of different user types in spreading news. The study found that Twitter played a key role in amplifying real-time information globally, especially during critical events. The Tunisian Revolution began with protests following the self-immolation of Mohamed Bouazizi, leading to the resignation of President Ben Ali. The Egyptian Revolution followed similar protests, with #Jan25 becoming a key hashtag. Both events saw extensive use of social media, with Twitter serving as a platform for coordination, news sharing, and discussion. The study highlights the symbiotic relationship between traditional media and individuals, as well as the role of social media in shaping news narratives. The research examined how information flows across different actor types, including mainstream media, journalists, bloggers, activists, and non-media organizations. It found that journalists and activists were key sources of information, with journalists often retweeting other journalists and activists retweeting journalists and bloggers. The study also noted that non-media organizations, such as WikiLeaks, played a significant role in spreading information. The findings suggest that Twitter enables a form of distributed journalism, where individuals and organizations collaborate to share news. The study highlights the importance of understanding how information flows on social media, particularly during critical events. It also raises questions about the role of social media in news production and the impact of networked information on traditional media. The research underscores the need for further study on the dynamics of information sharing on social media platforms.The 2011 Tunisian and Egyptian revolutions saw significant use of Twitter for information dissemination.
