Operating Systems: Market Shares since the 1970s

Looking at personal-use devices

Last updated: 2021

The below diagram shows the historical market shares of operating systems across personal devices (including smartphones), and the bottom shows the genealogy of the major operating systems. Many historical operating systems families are long dead, some other are somehow still alive but barely so (e.g. RISC OS, AmigaOS, Haiku/BeOS, ArcaOS/eComStation (OS/2)) or are not targetting the personal computing market anymore (e.g. Solaris, HP-UX, AIX, QNX, OpenVMS).

In some cases, OS names have been kept even though newer versions have not been based on the older versions at all. This includes Windows (versions up to Win 98 and Win ME based on MS-DOS, versions since Win 2000 based on NT), Blackberry OS (version 10 based on QNX), and macOS (version 10 based on the Unix-like Nextstep).
