MPAA admits mistake on downloading study

Hollywood laid much of the blame for illegal movie downloading on college students. Now, it says its math was wrong.

In a 2005 study it commissioned, the Motion Picture Association of America claimed that 44 percent of the industry's domestic losses came from illegal downloading of movies by college students, who often have access to high-bandwidth networks on campus.

The MPAA has used the study to pressure colleges to take tougher steps to prevent illegal file-sharing and to back legislation currently before the House of Representatives that would force them to do so.
