Folks in the Isle of Wight County in Virginia are looking to Wilson, NC, (which runs its own FTTH network called Greenlight) for inspiration as Charter will not expand broadband access locally. Interestingly, industry-backed Connected Nation would not consider these people to be unserved because they could buy wireless broadband cards that offer slow speeds at expensive prices and are still often capped at a monthly transfer of 5 Gigabytes ... which is to say not really a broadband option.
Charter will not expand their cable networks because
Charter requires that an area have a density of at least 30 rooftops per square mile in order to offer service, which leaves large swaths of the county, especially southern and western areas, without access.
Sounds like a good opportunity to investigate a publicly owned network.
