History
Blender was developed by the Dutch animation studio NeoGeo and Not A Number Technologies (NaN). It was initially distributed as shareware, but when NaN went bankrupt in 2002 it's community bought the source code for a one-time payment of €100,000. Today it is licenses under the GNU General Public License, and is insured by the Blender Foundation.
