Well, look at Verizon. Sure, not exactly the same as Verizon Wireless, but bear with me.
They started building out FiOS. Putting money where their mouth is.
But some MBA along the line figures that the expected ROI on it is beyond some arbitrary, magic number, and the FiOS rollout just stops.
Then, Verizon sells most of FiOS to Frontier. Is Frontier building out any more FiOS? Not in the area I live in.
At least in Beaverton, OR, you have neighborhoods or blocks with FiOS, and right across the street, nada. Lucky to have Comcast service of awesome.
