WIP!
World (or world-wide) broadcast is a possible technological service (possibly complementing the Internet) which could be implemented in a good society and whose main idea is to broadcast generally useful information over the whole globe so that simple and/or energy saving computers could get basic information without having to perform complex and costly two-way communication.
It would work on the same principle as e.g. teletext: there would be many different radio transmitters (e.g. towers, satellites or small radios) that would constantly be broadcasting generally useful information (e.g. time or news) in a very simple format (something akin text in Morse code). Any device capable of receiving radio signal could wait for desired information (e.g. waiting for certain keyword such as TIME: or NEWS:) and then save it. The advantage would be simplicity: unlike with Internet (which would of course still exist) the device wouldn't have to communicate with anyone, there would be no servers communicating with the devices, there would be no communication protocols, no complex code, no DDOS-like overloading of servers, and the receiving devices wouldn't waste energy (as transmitting a signal requires significant energy compared to receiving it -- like shouting vs just listening). It would also be more widely available than Internet connection, e.g. in deserts.
