The correct answer is the following: option D. In addition to the federal government's rules, corporate media outlets regulate their content primarily using their own agenda, viewer ratings and their competition. As the name indicates, corporate media responds not only to the federal government that regulates the laws and rules regarding mass communication, but also to the corporation and CEO's that own the business. Therefore each one of the corporate media enterprises existing has it own agenda and interests, and when choosing the content that will be used, that agenda is considered, among the conventional factors such as the viewer ratings and how the audience responds to the content aired, and how their competition behaves.
