In 2007, the U.S. core copyright industries combined accounted for $889.13 billion in "value added," or 6.44%, to the $13.81 trillion in gross domestic product, according to a study prepared by Stephen E. Siwek of Economics Inc. for the International Intellectual Property Alliance.

That's up from the $837.3 billion, or 6.354% it accounted for in 2006 when total U.S. gross domestic product totaled $13.2 billion. The U.S. core copyright industries in 2007 grew 6.2% over 2006's total, which outpaced the 4.8% growth in gross domestic product in those two years.

The IIPA consists of the Association of American Publishers, the Business Software Alliance, the Entertainment Software Assn. the Independent Film & Television Alliance, the Motion Picture Assn. of Americ the National Music Publishers Assn. and the Recording Industry Assn. of America, which in turn combined represent over 1,900 U.S. companies producing and distributing materials protected by copyright laws throughout the world, including all types of computer software such as business applications software and entertainment software, theatrical films, TV programs and textbooks, tradebooks, reference and professional publications and journals. The study was being presented today in Washington, D.C.

To put the numbers in perspective, the U.S. federal government's $979.3 billion in gross consumption expenditures and investments is only 10% greater than the core copyright value-add to GDP.

Other findings of the study show that the U.S. core copyright industries achieved annual growth rates in excess of 5.8% for the 2003-2007 years followed during the study. During that time, the core copyright industry outpaced the annual 3.64% growth rate if U.S. GDP.

The study also looked at the the role that total copyright industries - industries that support copyright such as retail stores that sell music, video and video games, and computer manufacturers play in gross domestic product. There it noted that the total U.S. copyright industry accounted for $1.43 trillion, or 11.05%, in value-added to GDP in 2007.

Looking at the core copyright industries importance in another way, the study found that these industries employed nearly 5.58 million people, who, on average, earned $73,544.00 a year. Those employees accounted for 4.05% of the total U.S. workforce of 137.6 million. Moreover the core copyright industries salaries outpaced the average salary of $56,817.00 per year.
