This document provides an overview and analysis of three municipal broadband networks: BVU Authority in Bristol, Virginia, EPB in Chattanooga, Tennessee, and LUS Fiber in Lafayette, Louisiana. Each of these communities built their own fiber optic networks to provide high-speed internet access after incumbent providers were unwilling or unable to upgrade networks to meet 21st century needs. The networks have faced opposition through lawsuits and legislation but have succeeded and generated economic benefits by attracting businesses and jobs to the communities. The document examines the history and challenges of each network and provides lessons learned for other communities considering building their own networks.
