What is GIMP? (Gruber, 2010)

History (Kimball & Mathis / GIMP.Org)
Originally stood for the General Image Manipulation Program
Created by Spencer Kimball and Peter Mathis in 1995 as a semester-long project at the University of California, Berkeley
First publicly released in January 1996
GIMP joined the GNU Project in 1997 GIMP and changed its acronym to GNU Image Manipulation Program

History (Kimball & Mathis / GIMP.Org)
GIMP is presently maintained and enhanced by a group of volunteers under the GNOME Project.
It was first created for UNIX systems, but can now be presently installed in Windows and MacOSX.
Ever since it was released, GIMP was rapidly adopted by a community of users who continue to create tutorials, artwork, share techniques, and contribute to the overall improvement of the program.
