The Recording Industry Association of America and AT&T have reached an agreement under which the enormous Internet service provider will help stop sharing music files online.

Greg Sandoval at CNET wrote about the agreement, which AT&T executive Jim Cicconi told an audience at the Leadership Music Digital Summit conference in Nashville that his company had started issuing notices to its customers to take down music files they had made available. This jibes with the new antipiracy policy of the RIAA, which was announced in December. The organization said at the time that it would stop suing people and focus on working with broadband ISPs to eliminate music file sharing. CNET had already reported that Comcast and AT&T were on board with the new program.

Sandoval said the program is probably a test run for a stricter version to come later on. It’s possible that repeat violations could prompt ISPs working with the RIAA to cancel accounts — which seems counterintuitive to ISPs, who need their customers to stick around.
