The room where the Internet started is located in a basement at UCLA, and it's been restored to something strongly resembling its original configuration. Their router, IMP, was a huge piece of equipment; their first transmission, to Stanford Research Institute, was intended to be: LOGIN. However, the system crashed after they typed the first two letters. Thus, the first Internet transmission was LO. But they tried again an hour later, and it worked.
By December 1969, there were four permanent nodes; by 1975, there were 57 IMPs. Six years later, there were 213. Who new it'd go so totally off the charts?
And yet, we have some of the slowest transmission speeds on the planet, today:
Its upload speeds are even worse. Globally, the U.S. ranks 42nd with an average upload speed of 6.31 Mbps, behind Lesotho, Belarus, Slovenia, and other countries you only hear mentioned on Jeopardy.
Why? Because big players like Comcast and Verizon have been permitted to establish de facto monopolies in most parts of the country. Absent competition, they've no incentive to upgrade.
