Emacs text editor marks 50 years since its 1976 debut at MIT
Emacs, one of the earliest full-screen text editors, began running on video terminals at the MIT Artificial Intelligence Laboratory in 1976 and remains in active use today. It grew out of the TECO editing language created by Dan Murphy in 1962 and Carl Mikkelsen's 1971 Control-R extension, which let programmers see live edits on screen rather than reprinting lines. The software was later ported to many operating systems, including a version Apple shipped with Mac OS X.
GoKawiil's interpretation of the reporting above, not reported fact.
Emacs's long development history helped spark a software-sharing culture at MIT that contributed to the later rise of the free software movement and GNU/Linux, suggesting its influence extends well beyond its use as an editing tool. Its continued use 50 years on indicates that the core interaction concepts it introduced have proven durable across generations of computing hardware and operating systems.
- Emacs first ran on MIT AI Lab terminals in 1976 and is still used today.
- It evolved from Dan Murphy's 1962 TECO editor and Carl Mikkelsen's 1971 Control-R add-on.
- Its community helped influence the free software movement and GNU/Linux.
