Year Of Internet’s Invention

The idea was to invent a network highly distributable and fault-tolerant design.
The idea of Baran was presented to DoD in the form of several reports. The officials at Pentagon took interest in the design and called AT&T (the only US telephone network monopoly at that time)to build a prototype, but AT&T laughed at the design solution of Baran and refused to implement it declaring the design impossible to be built. Years went by but DoD could not invent a better command-and-control system.
This network was implemented in December 1969. Since ARPAnet was the very first form of internet so we can call the year 1969 the year of internet’s invention.
