A broadcasting antenna in Stuttgart. Broadcasting is the distribution of audio or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a one-to-many model. [1]
Broadcasting can be performed as a high-level operation in a program, for example, broadcasting in Message Passing Interface, or it may be a low-level networking operation, for example broadcasting on Ethernet. All-to-all communication is a computer communication method in which each sender transmits messages to all receivers within a group. [1]
Teletext, or broadcast teletext, is a standard for displaying text and rudimentary graphics on suitably equipped television sets. [ 1 ] [ 2 ] Teletext sends data in the broadcast signal, hidden in the invisible vertical blanking interval area at the top and bottom of the screen. [ 3 ]
In computer networking and telecommunications, a broadcast communication network is a communication network which uses broadcasting for communication between its nodes. They take messages from a single sender and transmit to all endpoints on the network. For example, radio, television, etc.
In communication, media (sing. medium) are the outlets or tools used to store and deliver semantic information or contained subject matter, described as content. [1] [2] The term generally refers to components of the mass media communications industry, such as print media (), news media, photography, cinema, broadcasting (radio and television), digital media, and advertising.

At the receiver the pulses are audible in the receiver's speaker as beeps, which are translated back to text by an operator who knows Morse code. Radiotelegraphy was the first means of radio communication. The first practical radio transmitters and receivers invented in 1894–1895 by Guglielmo Marconi used radiotelegraphy. [5]
The invention of the Internet has also allowed breaking news stories to reach around the globe within minutes. This rapid growth of instantaneous, decentralised communication is often deemed likely to change mass media and its relationship to society. "Cross-media" means the idea of distributing the same message through different media channels.
Also AM radio or AM. Used interchangeably with kilohertz (kHz) and medium wave. A modulation technique used in electronic communication where the amplitude (signal strength) of the wave is varied in proportion to that of the message signal. Developed in the early 1900s, this technique is most commonly used for transmitting an audio signal via a radio wave measured in kilohertz (kHz). See AM ...
