Did you know that Guiglielmo Marconi sent the first ever radio transmission in 1896, so he's considered "the father of radio." Radio broadcasting is the transmission of audio (sound) over radio waves with the goal of reaching a large audience. Radio waves are transmitted by a land-based radio station in terrestrial radio broadcasting, whereas radio waves are broadcast by a satellite in Earth orbit in satellite radio broadcasting. A broadcast radio receiver is required to receive the material (radio). Stations are frequently associated with a radio network that distributes material in a standard radio format, whether through broadcast syndication, simulcast, or both. Radio stations use a variety of modulation techniques to deliver their programming: AM radio stations broadcast in AM (amplitude modulation), while FM radio stations broadcast in FM (frequency modulation) Newer digital radio stations broadcast in a variety of digital audio protocols, including DAB (digital audio broadcasting), HD radio, and DRM (digital rights management) (Digital Radio Mondiale. There are various types of radio broadcasting. AM and FM stations are among them. Commercial broadcasting, non-commercial educational (NCE) public broadcasting, and non-profit broadcasting, as well as community radio, student-run college radio stations, and hospital radio stations, are all available around the world. Many stations use AM technology to transmit on shortwave frequencies, which can be received thousands of miles away (especially at night). The BBC, VOA, VOR, and Deutsche Welle, for example, have broadcast shortwave to Africa and Asia. These broadcasts are extremely sensitive to weather and solar activity.
