DEFINING INFORMATION SOCIETY.........

Information society can be viewed as a society in which information technology is transforming every aspect of cultural, political, and social life and which is based on the production and distribution of information. It is characterized by the (1) pervasive influence of IT on home, work, and recreational aspects of the individuals daily routine, (2) stratification into new classes those who are information-rich and those who are information-poor, (3) loosening of the nation state's hold on the lives of individuals and the rise of highly sophisticated criminals who can steal identities and vast sums of money through information related (cyber) crime.

Information Society is a term for a society in which the creation, distribution, and manipulation of information has become the most significant economic and cultural activity. An Information Society may be contrasted with societies in which the economic underpinning is primarily Industrial or Agrarian. The machine tools of the Information Society are computers and telecommunications, rather than lathes or ploughs.
The idea of a global Information Society can be viewed in relation to Marshall McLuhan's prediction that the communications media would transform the world into a "global village."
