The Arpanet/Internet On This Day in History

This Day In History: The ARPANET officially changes to using the Internet Protocol, creating the Internet in 1983. There is a persistent myth out there that the government invented the internet, but in fact, the internet has private hands all over it. "IBM and ATT had major labs and were vitally interested in computers talking to one another as early as the late 1950s and early 1960s. Bell Labs invented UNIX in 1969; it made the internet possible. IBM invented FORTRAN and hard drives in 1956. Bell transmitted packet data over lines in 1958. Texas Instruments invented integrated circuits in 1958. In 1961 Leonard Kleinrock published a paper on packet switching networks. Bell Labs made the first modem in 1961. The mouse was invented in 1963. Digital Equipment Corporation produced the first minicomputer in 1964. In 1965 time sharing at MIT and mail command started. Intel began in 1968. The year 1966 saw the first use of fiber optics to carry telephone signals.
After the defense department got involved, it was still companies like Honeywell and Bolt Beranek Newman (a tiny company) that made headway on making the internet work."~Michael S. Rozeff
