How old is the internet?

Answer 1

ARPANet started in 1969, which would make the Internet 33 years old to date.

"The first ARPANet connection outside the US was established to NORSAR in Norway in 1973, just ahead of the connection to Great Britain. These links were all converted to TCP/IP in 1982, at the same time as the rest of the Arpanet."
If you consider adopting TCP/IP as the spawn of the Internet, it would be 24 years old to date.

"The first dial-up ISP, world.std.com, opened in 1989."
Or the first dial-up ISP, then 17 years to date.

"By 1990, ARPANET had been overtaken and replaced by newer networking technologies and the project came to a close. In 1994, the NSFNet, now renamed ANSNET (Advanced Networks and Services)"
Or 1994, when ARPANET offically stepped down and the Internet become an independent entity, would make the internet only 12 years to date.

What is ARPANet? It was the original backbone of the Internet (the first major structure that held it together).

The bottom line is that it's a matter of opinion the year the Internet started, but if you were to judge it based on ARPANet, it would be 33 years old.

Answer 2

1968 do the math
ARPA awarded the ARPANET contract to BBN. BBN had selected a Honeywell minicomputer as the base on which they would build the switch. The physical network was constructed in 1969, linking four nodes: University of California at Los Angeles, SRI (in Stanford), University of California at Santa Barbara, and University of Utah. The network was wired together via 50 Kbps circuits.
The actuall thing began in 1940s, ENIAC, but that was Hardware. ARPANET was the first Paket Switching Network.

Answer 3

Why do you ask?
Does it matter?
Vague question: When was it thought of / invented? or when was it first implemented or first publicly available or when did it become a truly World Wide Web i.e. available in say 60% of the World or counties, as I say bit hard to answer.
Idea? 70s or 80's, first used 80's, true global use 90's, I think?
As I say why worry or ask? Hope this helps!
