Try 18% penetration in Florida
Verizon stopped their forward FIOS deployment in the six county Florida market when approximtely 2/3 of their footprint was built out. Their penetration numbers were a woeful 22% initially and have churned to a miserable 18% (currently).
The incumbent cable operator for the majority of the Florida footprint is Bright House and they have handled the competition in a spectacular fashion. No installation fees, no long term contract and basically no bullshit. Verizon, not so much. Their attitude from the beginning was that of the proverbial 800 pound gorilla, without the usual manners. Most folks recognize Verizon's product is vastly superior but the market share remains with the incumbent.
Multiple dwelling unit build outs are also very slow, as the incumbents have signed a majority to long term bulk agreements.
Great idea; lousy implementation.
