Fair Use in the US Economy, September 2007, Computer & Communications Industry Association.

Je ne peux pas évaluer si la méthodologie est valable, mais l’exercice donne des résultats intéressants:

REVENUE
In 2006, fair use industries generated revenue of $4.5 trillion, a 31 percent increase over 2002 revenue of $3.5 trillion. In percentage terms, the most significant growth occurred in electronic shopping, audio and video equipment manufacturing, Internet publishing and broadcasting, Internet service providers and web search portals, and
other information services.

VALUE ADDED
Value added equals a firm’s total output minus its purchases of intermediate inputs and is the best measurement of an industry’s economic contribution to national GDP. In 2006, fair use-related industry value added was $2.2 trillion, 16.6 percent of total U.S. current dollar GDP.
