The world-wide digital content market which is largely comprised of photographs is US$1.5 billion annually and growing rapidly.
The largest stock agency, GettyOne based in Seattle has annual sales of $250 million (all figures US$) and in the last 5 years has spent $1 billion to buy 24 other agencies including: The Image Bank ($183 million, 30 million images), Tony Stone Images (1999 revenues $100 million) and Seattle based Photodisc (the largest on the Net), and has invested $50 million in digitizing some of their images. Some images are wholly owned, but GettyOne also pays royalties on many of its images. Photographers generally get 40-50 percent of the take.
