Scientists all over the world are exploring new technologies. Recently a British engineer developed a way to send high-speed voice and data signals on house hold electrical current, raising the possibility that Internet service could one day ride into homes and businesses over our existing infrastructure of electrical wires.
Technology such as DSL, cable modem, low orbit satellites, and power line transmission are exciting because they don't require us to dig up and replace the existing last mile of copper line that already connects most households in the world. Getting the web infrastructure in place world wide is a daunting task, but the advances on many fronts make it likely that the speed of improvement will surprise everyone in next decade.
