I’m not sure if it’s correct to talk about the internet as a revolution. The internet is in fact the result of a slow, hard earned evolution which has lasted about 30 years (!). Slowly, during these years, the costs of laying cables has dropped, the CPU was… well, invented (in 1974, the Intel 4004), processing power and memory have increased exponentially and the basic protocols were created (in 1972, the telnet protocol).
