Time Warner Cable Inc. last year became the first major U.S. Internet service provider to charge customers extra if they exceeded a certain amount of data traffic every month. That trial run apparently went well, because the company said Wednesday that it will expand the test to other cities.

Many ISPs have imposed caps on how much their subscribers can download each month. Time Warner Cable broke from the pack by setting relatively low limits -- for instance, 5 gigabytes for subscribers paying $30 a month -- and then charging $1 for each gigabyte over that limit.

Internet providers Verizon, Sprint and Time Warner Cable have agreed to block access to child pornography and eliminate the material from their servers, New York's attorney general said Tuesday.

The companies also will pay $1.1 million to help fund efforts to remove the online child porn created and disseminated by users through their services, Attorney General Andrew Cuomo said. The changes will affect customers nationwide.

Three of the nation's largest cable companies are quietly pulling the plug on a joint cell-phone venture with Sprint Nextel Corp., called Pivot.

Spokespeople for Comcast Corp., Time Warner Cable Inc. and Cox Communications Inc. said Wednesday they have stopped marketing the Pivot service and plan in the coming weeks to give their Pivot customers the option of switching to traditional Sprint mobile phone plans.

A spokeswoman for the fourth cable partner, privately held Advance/Newhouse Communications Inc., declined to comment.
