When NTSC color was being introduced into broadcast television, compromises had to be made for it to be compatible with previous black and white systems. The field rate was changed by 1/1.001 - from 60 to 59.94 frames per second. Older B&W TVs could receive color broadcasts and show them in B&W and the new color information could be encoded into the broadcast signal so that the new color TVs would show the broadcasts in color. Today, digital and HD signals have to fit in; 24, 30, and 60 frames/fields per second become 23.98, 29.97, and 59.94 to be compatible with existing NTSC formats and workflows.
