ALBANY, N.Y. - Three major Internet service providers have agreed with New York state officials to block online access to child pornography.

Attorney General Andrew Cuomo says Verizon, Sprint and Time Warner Cable will block child pornography newsgroups and eliminate the material from their servers. The companies will also pay more than $1 million to help fund efforts to remove child porn from the Internet.

The agreements follow an undercover investigation of child porn newsgroups and will affect customers across the United States.

Last year, Cuomo reached agreement with the social networking sites MySpace and Facebook to toughen protections against online sexual predators.
