So a while back, I heard that MSDOS was originally named QDOS (Quick and Dirty Operating System), and that it was later changed is MSDOS (Microsoft Disk Operating System). This was probably a marketing strategy to fix a rather unappealing name. My question is when did this change take place, and why did it take place specifically then?

          MS-DOS was indeed originally known as QDOS. The change in name occurred as a result of a change in ownership — from Seattle Computer Products to Microsoft.



          Tim Paterson, QDOS’ author, has documented this:




          The first versions of the operating system, called QDOS 0.10, were shipped in August 1980. QDOS stood for Quick and Dirty Operating System because it was thrown together in such a hurry (two man-months), but it worked surprisingly well. [...]



          In the last few days of 1980, a new version of the DOS was released, now known as 86-DOS version 0.3. [...]



          In July 1981, Microsoft bought all rights to the DOS from Seattle Computer, and the name MS-DOS was adopted. Shortly afterward, IBM announced the Personal Computer, using as its operating system what was essentially Seattle Computer's 86-DOS 1.14. Microsoft has been continuously improving the DOS, providing version 1.24 to IBM (as IBM's version 1.1) with MS-DOS version 1.25 as the general release to all MS-DOS customers in March 1982.




          IBM provided DOS with their PC as “PC DOS”.

          • Since this paragraph isn't really an answer to the question, I'll make it as a comment. MSDOS and PCDOS remained co-marketed but virtually identical products until 1993, with version 6.1 of PCDOS. IBM dropped Microsoft's QBASIC and added their long-time house editor E. (The had to, because the MSDOS editor was QBASIC with a different skin. It was a net gain because E is an extremely nice text editor.) For their part, Microsoft dropped IBM's DOS SHell in their version 6.22. With PC DOS 7, IBM added the Rexx language to make up for no BASIC.
