In Brazil: some 15-20 years ago one power company (Copel [1]) began to spread fiber optics with the power cables. They began in the backbone, then inside cities, and so on, as they were expanding or maintaining their business. Time passes and few months ago there was a spin-off using that infrastructure for telecom (Copel Telecom [2]).
