In recent years the world is facing two common issues one is information explosion and second population explosion. The explosion of information indicates knowledge. Today it has been noticed that the rapid development of new techniques and technology of information throughout the world 🌏 enhances the expansion of social changes. 

Modern techniques and technology are opening the doors 🚪 of knowledge 📗 day by day. The horizons of human awareness and perception are expanding very fast. On the other side explosion of knowledge provides information about the explosion of population and gives an idea of the reading population of students year by year. 

The growth of population and democratisation of education with different levels of motivation and aspirations. The growth of population is more serious in developing countries rather than the developed ones. India is a developing nation so facing both the issues of information and population explosion. So it can be said two general factors information,   and population explosion have created critical issues to deal with. 

There are many things to be learnt and more people to be taught. That's why the need for the universalization of education was felt. To deal with this problem effectively educational technology is consisting various modes of mass communication are essentially required. Both qualitative improvement and quantitative expansion of education can be facilitated and accelerated with the help of mass media under education technology. 

The mass media is playing a major role to handle the problems.  In the case of geographical, sociological, and economical diversities mass media comes out as an important means of education for all. 

Mankind gets a great deal of information from the universal mass media i.e. newspapers, TV, radio, magazines, journals, films, etc. Previously mass media in the form of definitive were only put to marginal and individualised use. But at present, the interest and endeavours of certain teachers have increased the use of different modes of media.

The method of communication means the way a piece of knowledge and information can be provided to all. The information and knowledge have been provided through radio, TV, phone, or published in print will appear different and have some different kinds of effects on everyone. 

John Dewey once stated that education couldn’t be limited to the teacher and can not be taught without a social environment.  So mass media plays such a strong force in the social environment of education.
