comment What does the term “channel” mean when used in regards to computer graphics?
There's a good overview by Alvy himself on his blog, here: alvyray.com/awards/AwardsAcademy96.htm . This would suggest that it was invented by Alvy Ray and Ed Catmull while they were at NYIT. Both later founded Pixar.
