To assume a sudden about-face on this is unrealistic because of precedential power of body of SC cases on media and constitutional guarantees of free expression. Desirability of such a change is arguable, also. Media are privately owned. The profit-orientation of media is consistent with capitalist structure of America and a successful attack on economic structure is unlikely. The media are serving existing power centers reasonably well, so demand for change is neither uniform nor strong.
Media are extremely profitable for owners.
Media serve politically powerful through campaign contributions, easy access through both news and advertising, and general support of the status quo. And do not overlook the fact that the media are popular with audiences. People like their TV and radio and music and movies and magazines and papers. No groundswell of dissatisfaction demanding change. When individuals enter organizations, the individuals change more than do the organizations.
