Media Hegemony
The concept of hegemony, which first was put forward by Antonio Gramsci (1971), refers to the moral, philosophical, and political leadership of a social group, which is not gained by force but by an active consent of other social groups through taking control of culture and ideology. During this process, the leading social group exerts its impact and gain its legitimacy mainly through social mechanisms such as education, religion, family and the mass media. Based on the definition of hegemony, media hegemony means the dominance of a certain aspects of life and thoughts by penetrating dominant culture and values in social life. In other words, media hegemony served as a crucial shaper of culture, values and ideology of society (Altheide, 1984). 
For example, TV news departments are considered as extensions of a capitalistic economic order (Hall, 1979). The products of the media contain messages that convey the nature of society, the nature of relation of production within the media and the domain of institutions and social process (Golding, 1979). Thus it is crucial to decode media to figure out the latent capitalist ideology within the products of the media, and more importantly to realize the role of the media as tools to produce merchandise in a late capitalist economic order.
The Fall of Hyperion (novel)
The government of the Hegemony is described in detail during the course of the novel, and its role in the fictional universe forms several portions of the plot. Planets with full membership status in the Hegemony select senators to serve in the upper house of the legislature, while the lower house consists of the All Thing, a forum accessible to all citizens through "implants" that connect humans to the "datumplane", one of the computerized realities resembling the World Wide Web. The executive branch consists of a chief executive officer elected by the Senate. At the time of the novel's events, Meina Gladstone serves as the Hegemony's chief executive officer. Despite the democratic tendencies of this parliamentary form of government, the Hegemony has at times taken actions viewed as tyrannous, using its small but elite military, known as FORCE, to invade the sea planet Maui Covenant, which had resisted integration into the Hegemony as a protectorate. Planets not incorporated into the Hegemony are nonetheless affected by it, and its ambassadors effectively administer some planetary governments. Still, some worlds, thought of as the "Outback", are sparsely settled. The planet Hyperion is viewed as part of the Outback, but is viewed with special regard due to the succession of strange events that have occurred on it since the formation of the Hegemony. These events include colonization efforts that have failed due to the menace of mysterious forces, correctly believed by many to have been the work of the Shrike.
