There is a greater mobility of population today than that was in the nineteenth or twentieth century because of the modem rapid means of transport. The life of the modem man is always on wheels. It is an important factor in the determination of spatial aspect of social relationships. Changes in communication devices (e-mail, internet, mobile phones etc.) have also influenced all aspects of social life (work, leisure, family, friendship, sports etc.) enormously. The basic function of all communication and transportation devices is the conquest of time and space. Shrinking space and time through the speed and low cost of electronic communication and air travel has developed a new phenomenon called ‘globalisation’.
Computers have affected almost all aspects of our life from reservations at the railway ticket window or registration for hospitals or colleges to the maintenance of accounts in banks and large business corporations. The popularity of science fiction (Harry Potter) and the films like Jurrasic Park are other indicators of the mythical and abundant power which technology can have in the modem world. Modern technology has also revolutionised the concept and quality of the systems of production, communication, social organisation and various processes of acculturation and symbolisation in societies. Technology helps in realising of our goals with less effort, less cost and with greater efficiency. Technology creates desire for novelty and innovation. Novelty is sought everywhere and transient interests give a corresponding character to social relationships. Technology has advanced in leaps and bounds over the last 25 years and the single invention that has had to greatest impact on our lives is the cell phone. It is now not only used as a means of communi-cation but it has enabled us to operate home appliances and entertainment devices, monitor our home’s safety, customise our internal home environment. In the light of these technical advances the anthropologist Peter Worsly (1984) was actuated to comment, “until our day, human society has never existed”, meaning that it is only in quite recent times that we can speak of forms of social association which span the earth. The world has become in important respects a single social system as a growing ties of interdependence which now affect virtually everyone.
The idea of ‘global village’ developed by Marshall McLuban (1960) reflects that the world is becoming more integrated in economic, political and cultural terms. (Above quoted from https://www.academia.edu/25227760/Theories_of_Social_Change?email_work_card=view-paper)
