Media systems (especially broadcasting) can be classified in two different types:
Public Media Systems: Government control over broadcasting through ownership, regulation, and partial funding of public broadcasting services.
Private Media System: Ownership and control lies in the hands of private companies and shareholders.
Both systems can exist in various forms, according to the degree of control by governments and private companies, with mixed systems (public and private) as the third main kind.
Whereas public media systems are usually at least partially funded by governments, private broadcasting solely relies on advertising revenue. Still also public media systems cannot exclude advertising as a source of revenue. Therefore both types are to a certain degree dependent on money coming in by advertisers.
And this implies consequences on the content provided by the media. As the attraction of advertisers becomes critically important, interests of the advertising industry frequently play a dominant role concerning the structure of content and the creation of environments favorable for advertising goods and services within the media becomes more and more common.
