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.
Grand strategy
Proponents of liberal hegemony favor a world order in which the United States is a hegemon and uses this power advantage to create a liberal international system and at times use force to enforce or spread liberal values (such as individual rights, free trade, and the rule of law). The United States strives to retain overwhelming military power, under a theory that potential competitors will not even try to compete on the global stage. It also retains an extensive network of permanent alliance commitments around the world, using the alliance system both to advance and retain hegemonic power and to solidify emerging liberal political systems. According to Posen, this strategy sees "threats emanating from three major sources: failed states, rogue states, and illiberal peer competitors." Failed states, in this view, are sources of instability; rogue states can sponsor terrorism, acquire weapons of mass destruction, and behave unpredictably; illiberal peer competitors would compete directly with the United States and "would complicate the spread of liberal institutions and the construction of liberal states." Support for liberal hegemonic strategies among major thinkers in both political parties helps explain the broad elite support for the 2003 invasion of Iraq and the 2011 intervention in Libya, even though U.S. military involvement in those conflicts had been initiated by presidents of different parties. The chief difference on foreign policy between Republican and Democratic proponents of liberal hegemony, according to Posen, is on support for international institutions as a means to achieving hegemony.
