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.

Reproduction and Distribution
Unlike copies of works made using analog copiers (photocopy machines, video recorders etc.) digital information can be reproduced extremely fast, at low cost and without any loss in quality. Since each copy is a perfect copy, no quality-related limits inhibit pirates from making as many copies as they please, and recipients of these copies have no incentive to return to authorized sources to get another qualitatively equal product. Additionally the costs of making one extra copy of intellectual property online are insignificant, as are the distribution costs if the copy is moved to the end user over the Internet.
Control and Manipulation
In cross-border, global data networks it is almost impossible to control the exploitation of protected works. Particularly the use of anonymous remailers and other existing technologies complicates the persecution of pirates. Also digital files are especially vulnerable to manipulation, of the work itself, and of the (in some cases) therein-embedded
