Comcast, Cablevision, Verizon, Time Warner Cable and other Internet service providers (ISPs) in the United States will soon launch new programs to police their networks in an effort to catch digital pirates and stop illegal file-sharing. Major ISPs announced last summer that they had agreed to take new measures in an effort to prevent subscribers from illegally downloading copyrighted material, but the specifics surrounding the imminent antipiracy measures were not made available. Now, RIAA chief executive Cary Sherman has said that ISPs are ready to begin their efforts to curtail illegal movie, music and software downloads on July 12.
