Internet service providers (ISPs) Comcast Corp and United Online Inc’s NetZero have agreed to block access to child pornography, the New York Attorney General’s office said on Tuesday.

The announcement comes a week after New York Attorney General Andrew Cuomo threatened to pursue legal action against Comcast Cable Communications LLC if it did not agree to reforms.

Several other ISPs, such as Verizon Communications Inc and Sprint Nextel Corp agreed in June to block Internet bulletin boards and websites nationwide that disseminate child porn.
