Verizon DSL: Changing Metrics

As markets change, so do metrics. It used to make sense to count "access lines." Not any longer. These days it makes more sense to count "revenue generating units." And at least in Verizon's case, it is starting to make less sense to count "digital subscriber lines," as FiOS increasingly becomes the lead broadband access product.

To be sure, broadband access markets also are nearing saturation. Most customers who want broadband already buy it. But as Verizon replaces copper plant with FiOS, DSL connections will decline, to be replaced with optical connections.

IGI Consulting points out that Verizon's rate of net additions of DSL subscribers has been slowing for a couple of years. Again, some of that is market saturation, some of it is FiOS replacement. But rates of increase for any product slow as demand is satisfied. Rates also decrease when product substitutes are offered.

In the first quarter of 2008 Verizon FiOS TV customers accelerated to 263,000, a sequential increase of 16 percent. Verizon now has more than 1.2 million FiOS TV customers,19 percent penetration of marketable homes. Over the past year Verizon has added more than 850,000 FiOS customers.

Total broadband subscribers, including DSL plus FiOS internet increased to 8.5 million up 1.1 million or 15 percent from a year ago. Verizon added 266,000 broadband customers in the quarter. FiOS Internet access customers now represent over 1.8 million subscribers, representing 23 percent penetration of marketable homes.
