Read the given passage carefully and answer the following question:

Today Internet is the largest electronic network on the planet connecting 1,000 million people in more than 100 countries. Communication through satellites emerged as a new area in communication technology since the 1970s after U.S.A and former U.S.S.R pioneered space research. Artificial satellites, now, are successfully deployed in the earth's orbit to connect even the remote corners of the globe with limited onsite verification. These have rendered the unit cost and time of communication invariant in terms of distance. This means it costs the same to communicate over 500 km as it does over 5,000 km via satellite. India has also made great strides in satellite development. Aryabhatt was launched on 19 April 1979, Bhaskar-l 1979 and Rohini in 1980. On 18 June 1981, Apple (Arian Passenger Payload Experiment) was launched through Arian rocket. Bhaskar. challenger and INSAT I-B have made long-distance communication, television and radio very effective. Today weather forecasting through television is a boon.

Cyberspace is the world of electronic computerised space. It is encompassed by the internet such as the World Wide Web (www). In simple words, it is electronic digital world for communicating or accessing information over computer networks without physical movement of the sender and the receiver... It is also referred to as the Internet. Cyberspace exists everywhere. It may be in an office, sailing boat, flying plane and virtually anywhere.

The speed at which this electronic network has spread is unprecedented in human history. There were less than 50 million Internet users in 1995, about 400 million in 2000 A.D. and over two billion in 2010. In the last few years there has been a shift among global users from U.S.A. to the developing countries. The percentage share of U.S.A. has dropped from 66 in 1995 to only 25 in 2005. Now the majority of the world's users are in U.S.A. U.K, Germany, Japan, China and India.

As billions use the Internet each year, cyberspace will expand the contemporary economic and social space of humans through e-mail, e- commerce, e-learning and e-governance. Internet together with fax, television and radio will be accessible to more and more people cutting across place and time. It is these modern communication systems, more than transportation, that has made the concept of global village a reality.

When did satellite communication technology emerge?

1970s

The correct answer is Option (3) → 1970s
