FIFTY YEARS OF THE PERSONAL COMPUTER OPERATING SYSTEM

Summary from the TLDR Web Dev newsletter

Gary Kildall created the first successful commercial operating system, CP/M, in 1974. His company, Digital Research Inc. (DRI), established CP/M as an industry standard, but later lost out to a Microsoft offering that copied its appearance and functionality. Despite this, Kildall continued to innovate, contributing to the development of important technologies such as CD-ROM encyclopedias and early computer animation.
