This study explores the profound impact of the transformation of the public communication space in Qatar in the era of digitization and social networking, and its role in changing the culture of communication. Based on communication theories, the research monitors the role of social networks in activating communication, and the emergence of these networks as a public domain to transcend the structural obstacles produced by urbanization patterns in the Arab Gulf Countries. The study concludes that there are indications that the public domain in Qatar has contributed to challenging the classic communication hierarchy that has long dominated the country. The study tracked two cases of “Hashtag” follow-up effects and various responses on Twitter, namely criticism of the content of the Islamic education curriculum and the condemnation of hosting an Israeli sports delegation.
