NBC's cable channels, including USA, Syfy and Bravo, posted a 7.7 percent increase in revenue, to $2.41 billion in the quarter. Its somewhat smaller broadcast business, which has been undergoing a reorganization, had a 11.6 percent increase, to $1.73 billion. Mr. McCormack attributed the broadcast unit's gains to "better ratings and higher retransmission consent fees." Comcast executives specifically credited "The Voice," the singing competition on NBC that has given the network some much-needed momentum. Distribution, not content, remains the biggest part of Comcast's business. Revenue for the distribution business, called Comcast Cable, was up 5.8 percent year-over-year, to about $10.5 billion, partly because it added 187,000 broadband subscribers in the second quarter. Comcast has been losing television subscribers to DirecTV and Verizon FiOS for years, and it lost another 159,000 in the second quarter. But the rate of loss has slowed lately, a point the company emphasized again on Wednesday.
