    Maybe BPL (Broadband over Power Lines)? X10 is from the 1970's, but BPL itself goes back as early as 1914. My neighbour's house is networked using homeplug, which I guess is the modern iteration of the concept. It works decently enough, and the devices are fairly inexpensive.

      Power-line communication
      Power-line communication (also known as power-line carrier), abbreviated as PLC, carries data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. A wide range of power-line communication technologies are needed for different applications, ranging from home automation to Internet access which is often called broadband over power lines (BPL). Most PLC technologies limit themselves to one type of wires (such as premises wiring within a single building), but some can cross between two levels (for example, both the distribution network and premises wiring). Typically transformers prevent propagating the signal, which requires multiple technologies to form very large networks. Various data rates and frequencies are used in different situations. A number of difficult technical problems are common between wireless and power-line communication, notably those of spread spectrum radio signals operating in a crowded environment. Radio interference, for example, has long been a concern of amateur radio groups. Basics Power-line communications...

      Broadband over power lines
      Broadband over power lines (BPL) is a method of power-line communication (PLC) that allows relatively high-speed digital data transmission over public electric power distribution wiring. BPL uses higher frequencies, a wider frequency range, and different technologies compared to other forms of power-line communications to provide high-rate communication over longer distances. BPL uses frequencies that are part of the radio spectrum allocated to over-the-air communication services; therefore, the prevention of interference to, and from, these services is a very important factor in designing BPL systems. There are two main categories of BPL: in-house and access. In-house BPL is broadband access within a building or structure using the electric lines of the structure to provide the network infrastructure. Access BPL is the use of electrical transmission lines to deliver broadband to the home. Access BPL is considered a viable alternative to Cable or DSL to provide the 'final mile' of broadband to end users. History BPL is based on PLC technology developed as far back as 1914 by the US telecommunications company AT&amp...

      X10 (industry standard)
      X10 is a protocol for communication among electronic devices used for home automation (domotics). It primarily uses power line wiring for signaling and control, where the signals involve brief radio frequency bursts representing digital information. A wireless radio-based protocol transport is also defined. X10 was developed in 1975 by Pico Electronics of Glenrothes, Scotland, in order to allow remote control of home devices and appliances. It was the first general purpose home automation network technology and remains the most widely available. Although a number of higher-bandwidth alternatives exist, X10 remains popular in the home environment with millions of units in use worldwide, and inexpensive availability of new components. History In 1970, a group of engineers started a company in Glenrothes, Scotland called Pico Electronics. The company developed the first single chip calculator. When calculator integrated circuit prices started to fall, Pico refocused on commercial products rather than plain ICs. In 1974, the Pico engineers jointly developed an LP record turntable, the ADC Accutrac 4000, with...
