Trade groups representing the U.S. entertainment industry said on Thursday that new CDs, DVDs and video games would carry a stark warning about the legal penalties for unauthorized copying as part of an effort to combat digital piracy.

The new warning label, which was announced at a news conference on Thursday, will carry the seal of the Federal Bureau of Investigation.

The new and more prominently displayed warning will read: "The unauthorized reproduction or distribution of this copyrighted work is illegal. Criminal copyright infringement, including infringement without monetary gain, is investigated by the FBI and is punishable by up to five years in federal prison and a fine of $250,000."

The program was announced jointly by officials of the FBI, the Motion Picture Association of America, which represents Hollywood studios, the Recording Industry Association of America, which represents the major music companies, and the video game industry's Entertainment Software Association.
