$5.8B royalty from licensed products
From a BusinessWeek story on Ebony magazine and its publisher:
According to a 2003 study commissioned by Riotto's organization LIMA and conducted by researchers at the Yale School of Management and Harvard Business School, more than 5.8 billion in royalty income was generated from licensed products. About 45 million was generated from publishing alone, with the strongest showings coming from entertainment/character licenses (about 43 percent share of market), and trademarks/brands and fashion a close second and third (18 percent and 14 percent respectively).
And recently Kleiner Perkins invested in Zazzle that allows you to create your own personalized t-shirts etc. using licensed products.
