Most musicians and artists say the Internet has helped them make more money from their work despite online file-trading services that allow users to copy songs and other material for free, according to a study released on Sunday.

Recording labels and movie studios have hired groups of lawyers to pursue（追究）networks like Kazaa, and have sued thousands of individuals who spread out copyrighted material through such networks.

But most of the artists surveyed by the nonprofit Pew Internet and American Life Project said online file sharing did not concern them much.

Artists were divided on the rewards of peer-to-peer networks, with 47 percent saying that they prevent artists from earning royalties（版税）for their work and another 43 percent saying they helped promote and spread their material.

But two-thirds of those surveyed said file sharing caused little threat to them, and less than one-third of those surveyed said file sharing was a major threat to creative industries. Only 3 percent said the Internet hurt their ability to protect their creative works.

 “What we hear from a wide range of artists is that, despite the real challenges of protecting work online, the Internet has opened new ways for them to exercise their imaginations and sell their creations,” said report author Mary Madden, a research specialist at the Pew Internet and American Life Project.

The nonprofit group based its report on a survey of 809 self-identified artists in December 2003.
