In economics, a public good is a good that is both non-excludable and non-rivalrous in that individuals can not be effectively excluded from use and where use by one individual does not reduce availability to others. Examples of public goods include fresh air, clean water, knowledge, lighthouses, open source software, radio and television broadcasts, roads, street lighting. Public goods that are available everywhere are sometimes referred to as global public goods. -wikipedia
Many have suggested that the Internet is the first real global public good. Many also suggest that this is injeopardy due to increasing pressure from private-sector companies and other kinds of political pressure and lobbying.
Internet Governance plays a crucial role in this. Government and non-Government organizations throughout the world haven take on this challenge to protect the Internet for all in detriment of nobody.
