Kolkata: Ever since US programmer Ray Tomlinson sent the first email 40 years ago, the new communication tool has taken the world by storm, but it took another 20 years or so to reach the Indian shores, Indian scientists recall. "In October 1971, Tomlinson wrote a software and was able to transfer a message from one computer to another, making it the first networked email, much before the advent of what we now know as Internet," Sugata Sanyal, former professor of computer science, Tata Institute of Fundamental Research (TIFR), Mumbai, said.
Tomlinson's 'invention' came while improving a program called SNDMSG, which was in use since 1960s, that allows a user to compose, address, and send a message to other users' mailboxes in a single computer. The first email, containing a 'forgettable' message, was sent between two computers that were literally side by side with their only physical connection being through the ARPANET, one of the first computer networks of the world.
Sanyal, now Advisor, Corporate Technology Organisation of TCS, said many Indians studying or researching in the US around that time had their first experience with email through ARPANET or the BITNET, a network used to exchange emails by academics of universities across the US. Rajiv Gavai, professor of the Theoretical Physics Department, TIFR, was one of those Indians. As a post-doctoral fellow in Brookhaven National Laboratory, New York, in the early '80s, he used emails of both ARPANET and BITNET to interact with co-authors who were several miles away.
Gavai was so impressed by "the ease of collaborative work, without use of the then expensive fax machines or the too-cryptic telex machines", that he initiated setting up of a similar BITNET-based academic network in India. After the government nod, five IITs (Bombay, Delhi, Kanpur, Kharagpur and Madras), IISc (Bangalore), National Center for Software Technology (NCST) of Bombay and DoE were involved in the ERNET project, said Ramani, the founding director of NCST.
"In 1986, a dial-up link for email exchange was set up between NCST and IIT Bombay. Very soon all ERNET partners were on dial-up ERNET email and academics in these institutions started sending emails to all over the world," he said. When there was no Internet service providers in the country, public or private, ERNET informally gave email facilities to software companies, said Ramani. But what was the reaction of the common people on these pathbreaking achievements?
"In the beginning, people did not have much idea about email. A sure-shot method to convince one was to describe how easy and cost-effective it would be to contact with his/her son or daughter abroad," said Swapan Kumar De, former head, Computer and Informatics Group, Variable Energy Cyclotron Centre (VECC), Kolkata.
"In the eastern region, ERNET was first installed in VECC. From there it was spread to other institutes in Kolkata and other states," said De, the pioneer in initiating ERNET in eastern India. By 1991, the ERNET community crossed 1000 and hundreds of persons started using email in these sites, said De, adding that at that time, the initial investment to have ERNET mail was around Rs 30,000, without a printer.
And now, after two decades, a recent survey by the Internet and Mobile Association of India has predicted that Internet subscriber base in the country is expected to reach 150 million by the end of this year.
