The Unix scene

Unix was a scene.

Date Event Unix scene members Unix-influenced users
1966 Thompson joins Bell Labs. Unix doesn't exist yet. 0 0
1965-1969 Thompson and Ritchie work on Multics project at Bell Labs (joint project with MIT and GE). 0 (not Unix yet) 0
1969 Bell Labs withdraws from Multics project. 0 0
1969 (summer) Thompson writes Space Travel game on PDP-7, designs simple file system. ~2 ~2
1970 First running Unix system (Thompson + Ritchie). Name changes from "Unics" to "Unix". ~3 ~3
1971 First Edition Unix released internally at Bell Labs. Small group using it: Thompson, Ritchie, McIlroy, few others in the research group. ~12 ~15
1972 Ritchie begins developing C language. Unix group at Bell Labs growing - more researchers adopting it. ~30 ~75
1973 (summer) Unix rewritten in C (makes it portable). McIlroy suggests pipes, Thompson implements in one night. Philosophy crystallizes. ~60 ~150
1973 Fourth Edition Unix. Being presented at conferences. Papers published. Philosophy getting articulated. ~100 ~300
1974-1975 AT&T begins distributing to universities (nearly free, with source code). Berkeley gets it. ~300 ~1,500
1975 First USENIX conference (40 attendees, 20 institutions). Community infrastructure begins forming. ~400 ~2,000
1978 First BSD (Berkeley Software Distribution) release (30 copies distributed). Growing university adoption. ~900 ~4,500
1979 Seventh Edition Unix (V7). Widely considered the most important Unix. ~1,500 ~7,500
1980 Usenet begins. Community infrastructure emerges - people can share code and discussions asynchronously. ~2,000 ~12,000
1983 TCP/IP added to BSD (4.2BSD). BSD development accelerates. Unix becomes the internet OS. ~7,500 ~75,000
1983 AT&T System V Release 1. AT&T commercializes Unix. Scene begins fragmenting between commercial Unix and BSD. ~10,000 ~150,000
1984 45,000 Unix systems installed, 940 Usenet hosts. Scene thriving but fragmenting. ~15,000 ~300,000
1985 Microsoft Windows 1.0 released. Not Unix-based (runs on top of DOS). ~40,000 ~2M
1985-1988 PEAK. USENIX conferences draw ~3K attendees. CS degrees peak at 42K/year. Scene at maximum size but losing coherence. ~40,000 ~2M
1988 Unix Wars begin. Rival consortia form (OSF vs Unix International). Scene fragmenting into incompatible camps. Fragmenting ~4M
1989 NeXTSTEP released by Steve Jobs' NeXT Computer. Unix-based (BSD foundation). ~45,000 (fragmenting) ~4M
1991 Linux kernel first released by Linus Torvalds. Unix-like but not Unix. Free and open source. NEW scene begins, separate from Unix. Unix: ~20,000, Linux/BSD: ~300 ~15M
1993 Windows NT released. Not Unix. Begins Microsoft's dominance in corporate computing. Commercial Unix systems (Solaris, HP-UX, AIX) start declining. Unix: ~15,000, Linux/BSD: ~3,000 ~30M
1995 Windows 95 released. Huge commercial success. Not Unix. Unix becomes increasingly niche in desktop/consumer markets. Original Unix scene dissolves - BSD CSRG closes after 20 years. Unix scene ended, Linux/BSD: ~30,000 ~40M
1997 Apple acquires NeXT. NeXTSTEP becomes foundation for future macOS. Unix: ~7,500, Linux/BSD: ~75,000 ~65M
2001 Mac OS X released. Unix-based (BSD + NeXTSTEP). First mainstream consumer Unix. Unix: ~7,500, Linux/BSD: ~500,000 ~125M
2007 iPhone released. Runs iOS, which is based on macOS (thus Unix-based). Unix in billions of pockets, users unaware. Unix: ~10,000, Linux/BSD: ~2M ~300M
2008 Android released. Based on Linux kernel. Unix: ~10,000, Linux/BSD: ~3M ~750M
2014-2015 Unix DNA reaches billions of users via smartphones. Most people use Unix-descended systems daily without knowing. Unix: ~10,000, Linux/BSD: ~8M ~2.5B
2025 Today. Commercial Unix systems (Solaris, HP-UX, AIX) nearly extinct. Replaced by Linux in enterprise, macOS in consumer/creative markets, Windows in corporate. Original Unix scene dissolved - descendants (Linux, macOS) dominate computing but are too large/diffuse to be a "scene". Unix: ~10,000, Linux/BSD: ~10M ~6.5B

The scene dissolved, but The Unix philosophy won — it's everywhere. Most servers run Linux. Macs and iPhones run Unix. Android runs Linux. Windows is the outlier. Today most of humanity uses Unix-descended systems.
