Between 2004-2009, nearly $42 Billion worth of Sony PSP and Nintendo DS games were pirated , according to The Computer Entertainment Suppliers Association (CESA) . This figure is only for Sony PSP and Nintendo DS games.
To arrive at these figures, researchers checked download counts at the top 114 piracy sites for the Japanese versions of the top 20 software titles from 2004 to 2009. They calculated the total Japanese figure by factoring in the price of the games and the ratio of sales for the top 20 to the whole market. To get the worldwide figure, they multiplied by four under the presumption that Japan accounts for 25% of of the world’s software market.
Peer-to-peer sharing methods like Winny and Share were not included in the investigation. CESA notes that because of this, the actual figures could be much higher.
CESA also reported a number of other findings from its investigations. The country with the most servers hosting piracy sites is America. China is number 2. Together, these two countries account for 60% of all servers. Researchers weren’t able to find any domestic servers.
America is number one in terms of number of accesses to piracy sites. Japan is number 2, with China third
