According to this AP news story, the MPAA nows says that there was a computational error in earlier results indicating that college student file sharing was a major source of pirated media. The MPAA said that it
has told education groups a "human error" in that survey caused it to get the number wrong. It now blames college students for about 15 percent of revenue loss.
The MPAA says that's still significant, and justifies a major effort by colleges and universities to crack down on illegal file-sharing. But Mark Luker, vice president of campus IT group Educause, says it doesn't account for the fact that more than 80 percent of college students live off campus and aren't necessarily using college networks. He says 3 percent is a more reasonable estimate for the percentage of revenue that might be at stake on campus networks.
