Charter

One important thing to remember is that the legal campaign pursued by Voltage Pictures and the other companies Dunlap represents is that they have nothing to do with the Motion Picture Association of America, the trade group representing the largest Hollywood studios.

The MPAA and RIAA are pursuing much different antipiracy strategies. They have tried convincing ISPs to send warning letters to first-time offenders. In the case of chronic pirating, the MPAA and RIAA want ISPs to suspend or even terminate service.

When it comes to sending letters, ISPs have begun cooperating. One reader, who wished to remain anonymous, sent CNET a copy of a letter he recently received from Charter Communications, the reader's ISP. The reader was notified that NBC Universal had accused him or her of file sharing the TV show "House."

As for actually shutting off someone's service, many of the top ISPs have steered clear.
