Kodak classifies all of their black and white films as "Professional" films. Its actually been that way for a long time, before digital became popular, since the average consumer only shot color.
Portra and other films are also considered "professional" products. I laughed and breathed a sigh when I looked around the "Business to Business" section of their site: all of the products I care about are what they're calling B2B products, and they want to become a B2B company. (;
