Founded on 15 August 1997 by Mena Quintero and Miguel de Icaza, GNOME has grown to become one of the two more widely used desktop environments by Linux users.

The project was started because the main desktop environment existing at the time, KDE, was based on QT, a library that was not released under a free software licence.
Version 1.0 was released in 1999. Since then there have been 33 stable releases.
The latest stable release, GNOME 3.24 or Portland, included new features like the GNOME Recipes application and Night Light, which helps users avoid eyestrain.
The upcoming version of GNOME 3.26 or Manchester is scheduled for release in September.
The GNOME project has more than 6000 contributors, and includes about eight million lines of code.
The name GNOME is an acronym for GNU Network Object Model Environment.
