The American Cable Association has profiled Tacoma's Click! network. Click! is an HFC network owned by the city, via the public power utility. Tacoma Power only offers one retail service: cable television. Voice and broadband data services are provided by independent services providers who use the network on an open access basis.
The network has been quite successful. Some 25,000 households subscribe and it has kept competitor rates (Comcast, for instance) far lower than nearby Seattle, for instance. I previously noted the economic development victories attributable to the network.
