FTTH in the US

The FTTHCouncil of North America recently released a report on the status of FTTH in North America. One of the biggest surprises was that Verizon accounts for a very large percentage of FTTH.

So the troubling question is, why is Verizon the only provider building out their network in any perceptable amount? Surely other service providers are building out their systems. If you know of any please post.
