Discovering internet porn
Yeah but, the trouble there was you could only hint at lewdness with a resolution of 1024 x 768. It doesn't start to get really smutty until you hit at least 6 MP. (3000 x 2000).
On a more technical note, Nikon's 1st consumer DSLR, the 6 MP D-70 wasn't released until 2004, a scant 12 years ago. Film scanning had its limitations, and internet bandwidth simply wasn't up to the task of transmitting larger images. So the pictures you'd find were usually scaled to the most common monitor resolution of the period, 1024 x 768.
Today, the undisputed master of "boor-nography", Peter Hegre, is using a studio back at about 10,000 x 7500! Dear God, I certainly wish he'd give it a rest.
