History of internet : Do you want to know which organization is responsible for the emergence of Internet ? Let us have a comprehensive overview of the history of Internet.
The internet originated with the development of computers during the period from 1950s and 1960s.
In 1957, the USSR (Union of soviet socialist Republics) launched Sputnik, the first artificial satellite. In response to this technological achievement, the US department of defense established Advance 
Reasearch project Agency (ARPA) This agency facilitated the technical research.

• In 1969, the Advanced Research Project Agency (ARPA) designed a network of four computers to exchange and share their data. The first official network nodes were UCLA (university of california, Los Angeles); SRI (Standford Research Institute), UCSB (university of california, santa barbara), and the university Utah. The first node to node message was sent from UCLA to SRI. This network was called ARPANET (Advanced Research project agency network). The purpose was to distribute information between geographicall dispersed computers. Later on. US Department of Defense allowed the Universities to join this network for sharing hardware and software resources. The internet grew in leaps and bounds during the 1970s.
• In 1971, more nodes joined the network. These new nodes included harvard and NASA.
• In 1974, data was transmitted more efficiently with the development of TCP ( Transmission control protocol and later on IP ( internet protocol ) technology ws developed.
• In 1982, Internet technology protocols were used, commonly known as TCP/Ip(Internet protocol).This led to one of the first definations of internet. being a connected set of networks.
• Tim Berners-Lee developed the WWW (world wide web) in 1991.
• Earlier, internet ws used by engineers, scientists and computer experts for research purpose. Gradually the network was made accessible to private agencies and general public. people started using it for sending messages and files between the computers.
• The organizational structure of Internet has steadily evolved; after around four decades of internet users in india alone and 1 billion users around the world.
• In india, internet services started on 15th aug 1995 through a govt owned company VSNL (videsh sanchar nigam limited). Private Internet services providers like Airtel,Reliance, Sify, Tata etc. have also been allowed to provide internet services.
