Time Warner Cable this week announced it signed up its’ nine-millionth Road Runner customer, making the company the third largest Internet Service Provider in the United States.

Broadband service continues to grab an increasing share of business for the nation’s cable operators, even as they continue to lose video subscribers.  During the last quarter of 2009, Time Warner lost 105,000 video subscribers  but added 120,000 residential high-speed Internet subscriptions.

Nine million subscribers paying even a promotional rate of $30 a month earns the company $270 million dollars a month — $3.24 billion dollars a year.

“This is a great milestone for Time Warner Cable, and it further proves that our customers enjoy the speed and content our HSD products deliver, as well as the value seen when bundling this service with our video and phone offerings,” said Landel Hobbs, COO of Time Warner Cable. “High Speed Data continues to be a growing part of our business and we look to keep adding new features and further enhance speeds as we move through 2010.”

The company claims it has not lost a significant amount of business to its most-feared potential competitor, Verizon’s fiber to the home network FiOS.  But the company is installing DOCSIS 3 upgrades to increase speeds in markets where FiOS competes for broadband customers.  Cable industry experts suggest broadband is becoming a mature industry, and growth from customers new to the high speed experience are fewer in number.  A strong percentage of new Time Warner Cable broadband customers come from landline customers defecting from relatively slower DSL service from phone companies.

As interest in high bandwidth applications like streaming video increase, DSL service can prove a frustrating experience for those stuck with lower speeds.  Despite claims by some phone companies that consumers don’t care about broadband speed, Time Warner Cable will offer increased speed tiers and upgrades in most of its competitive markets in 2010 based on the assumption many customers do.
