Too Long; Didn't Read
If the previous two decades were the dark ages, the 1970’s were the Renaissance; a bridge between the classical era of computing and the modern era of programming. It was a time of great change for Western society in general and the world of programming was no exception. Programming was on the verge of becoming the activity we know today; it was becoming possible to write code without an intimate knowledge of the computer hardware. CRT based VDTs first introduced with IBM’s System 360 and originally costing as much again as the computer itself, became affordable and common. New programming languages changed the way people worked, and by the end of the decade, personal computers became available at reasonable prices.
