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.
Offensive realism
John Mearsheimer summed up this view as follows: "great powers recognize that the best way to ensure their security is to achieve hegemony now, thus eliminating any possibility of a challenge by another great power. Only a misguided state would pass up an opportunity to be the hegemon in the system because it thought it already had sufficient power to survive." Accordingly, offensive neorealists such as Mearsheimer believe that a state's best strategy to increase its relative power to the point of achieving hegemony is to rely on offensive tactics. Provided that it is rational for them to act aggressively, great powers will likely pursue expansionist policies, which will bring them closer to hegemony. Since global hegemony is nearly impossible to attain due to the constraints of power projection across oceans and retaliation forces, the best end game status states can hope to reach is that of a regional hegemon dominating its own geographical area. This relentless quest for power inherently generates a state of "constant security competition, with the possibility of war always in the background". Only once regional hegemony is attained do great powers become status quo states.
