For the past few years, Selling Stock has maintained a list of the world's leading sellers of stock photography and illustration. An updated version of this list can be found here.
We have placed the companies in three broad groups, based on our estimates of their gross annual revenue. There are 14 companies in Group A we believe have annual revenues in excess of $20 million. We have listed them, as best we can determine, in descending order based on size.
The companies in Group B have revenues between $5 million and $20 million. Group C companies have revenues are between $1 million and $5 million. The Group B and C companies are listed in alphabetical order, given the difficulty of determining precise revenues.
