Step-by-step explanation:
The dominance model of media power refers to the control and influence exerted by powerful individuals and social institutions over the media. These individuals and institutions have the ability to shape and control the content that is available to the public, thereby influencing public opinion and policy.
A few multinational conglomerates dominate the mass media, owning major television networks, production companies, movie studios, magazines, book publishers, recording companies, and even significant ownership interests in internet media. This consolidation of media ownership limits diversity and choice in information sources, and can lead to a concentration of power and influence.
