The company snatched up the 13th largest cable operator, Insight Communications, back in 2012. In 2011, Time Warner acquired New Wave Communications, getting some 70,000 customers in the Kentucky and Tennessee area. However, Cablevision Systems Corporation (NYSE:CVC) is family-owned. The Dolan family owns some 75% of the company and has shown no interest in selling the cable operator. Time Warner Cable Inc (NYSE:TWC) is expected to see revenue growth of 5.5% in 2013 and another 4.5% in 2014. Not too bad for a dying industry. Yet, the problem is under the hood. The cable company expects that programming costs could increase another 10% in 2013. If so, the impact on operating margin could be a 0.5% to 1% decline, pushing free cash flow down to $2.3 billion, versus $2.55 billion in 2012. Hedge fund trade Billionaire Mario Gabelli doubled down on Cablevision Systems Corporation (NYSE:CVC) earlier this year.
