Fair use exceptions to U.S. copyright laws account for more than $4.5 trillion in annual revenue for the United States, according to a report issued on Wednesday by the Computer and Communications Industry Association.

“Much of the unprecedented economic growth of the past 10 years can actually be credited to the doctrine of fair use, as the Internet itself depends on the ability to use content in a limited and nonlicensed manner,” CCIA president and CEO Ed Black said in a statement. “To stay on the edge of innovation and productivity, we must keep fair use as one of the cornerstones for creativity, innovation, and, as today’s study indicates, an engine for growth for our country.”
