Who created vi and VIM, and what is their history?

Bill Joy wrote vi in 1976; Bram Moolenaar wrote Vim ("Vi IMproved") in 1991 as its modern successor.

That fifteen-year gap hides why vi feels so alien at first. Joy built it to be driven over a 300-baud terminal connection, where every keystroke was slow to transmit and many keyboards had no arrow keys at all. Making the letter keys move the cursor — instead of inserting text — let you edit with the fewest possible keypresses, never leaving the home row. That hardware constraint is the origin of vi's modal design, and Vim inherited it wholesale; it's why the muscle memory still pays off five decades later.

Bill Joy (vi - 1976)

  • Co-founder of Sun Microsystems
  • Developed the text editor vi
  • Major contributor to BSD Unix
  • Visionary for Open Source and network technologies

Bram Moolenaar (VIM - 1991)

  • Main developer of Vim
  • VIM = improvement of vi with many additional features
  • Strong commitment to Free Software
  • Made Vim one of the most popular text editors worldwide

Both significantly shaped the world of text processing and software development.
