Video Games Add $18 Billion To U.S. GNP

Written by a pair from the Brookings Institution and Georgetown University but funded by the Entertainment Software Association (ESA), a game industry group, the study said that 2004 sales directly contributed $10.3 billion to the country’s gross national product. Adding in another $7.8 billion for spending on such ancillary products and services as a portion of high definition television sets and part of broadband Internet revenues brings the grand total to $18.1 billion.
