Target: The Cubicle

The RIAA, the Motion Picture Association of America, and similar groups have stepped up their antipiracy efforts, writing to Fortune 1000 firms urging them to do whatever it takes "to ensure that their networks are not being misused to infringe copyrighted works."

Most music downloaders use high-speed Internet connections to access P2P services. While only 16 percent of homes have these high-speed connections, 57 percent of all employees can use one at work, says a recent report from Jupiter Media Metrix, an Internet and new-technology research firm. By 2005, Jupiter predicts, this will increase to 87 percent of all employees.

Target: College Dorms

The recording industry association has another prime battlefield in the music piracy war: academia. They sent a letter to 2300 college presidents in October, pushing the schools to "inform students of their moral and legal responsibilities to respect the rights of copyright owners" when using the universities' networks.

Six higher education associations have joined in the effort, urging college campuses to set rules against illegal online piracy. In a separate letter, they encourage universities to reexamine their existing copyright policies, taking into account P2P software, says John Vaughn, executive vice president of the Association of American Universities.
