Suddenlink, which has 1.2 million TV subscribers, became the largest U.S. cable operator to carry Netflix on its cable boxes, the cable company said on Tuesday. Suddenlink said it is the seventh-largest cable operator in the United States, serving customers in states such as North Carolina, Texas and Louisiana. The news comes two weeks after three smaller U.S. cable operators became the first to carry Netflix on set-top boxes provided by TiVo, including RCN.
