A new alert system, rolling out over the next two months, will repeatedly warn and possibly punish people violating digital copyrights. The Copyright Alert System was announced last July and has been four years in the making.

If you use AT&T, Cablevision, Comcast, Time Warner, or Verizon as your Internet service provider, you could receive the first of one of these notes starting in the next two months.

The Internet provider is delivering the message, but the legwork is being done by the copyright owners, which will monitor peer-to-peer networks such as BitTorrent.
