Yes, it is true that the rapid social change is a new concept or a new phenomenon in human history. The reasons behind stating it a new phenomenon are –

a) The evidences from past show that human beings are in existence from 5,00,000 years but the civilization started only 6000 years ago; that means it took more than 4,00,000 years to introduce civilization among the human beings.

b) Even after being social socialized the changes at a constant pace started from just last 400 years.

c) The actual acceleration in the pace of changes took place in last 100 years due to advancement in technology and the industrial revolution.

d) If we see the period of previous 50 years, we can say that during first 30 years that change was slow than the pace of change in these last 20 years.

So we can say that the speed of change is increasing with every day, with every decade and the human beings are progressing towards development with every passing day, hour, and minute.
