Electronic media refers to any type of device or medium that utilizes electronics or electromechanical energy for the end-user to access its content. Its history dates back to the late 18th century, beginning with the advent of wire and transmission lines, followed by innovations like the telegraph, fax machine, and telephone in the 19th century. The 20th century saw revolutionary developments like fiber optics, radio transmission, LED and LCD displays, and wireless communication. Signal processing and information storage evolved with the invention of capacitors, Morse code, electronic modulation, and digital encoding methods. Electronic media formats diversified with the introduction of vinyl records, digital audio files, and various video formats. The field also witnessed significant advancements in audio and video recording technologies. Interactivity[1] was enhanced with the development of control panels, input devices, and game controllers. Today, electronic media plays a vital role in communication, entertainment, data transmission, and information storage.
Electronic media are media that use electronics or electromechanical means for the audience to access the content. This is in contrast to static media (mainly print media), which today are most often created digitally, but do not require electronics to be accessed by the end user in the printed form. The primary electronic media sources familiar to the general public are video recordings, audio recordings, multimedia presentations, slide presentations, CD-ROM and online content. Most new media are in the form of digital media. However, electronic media may be in either analogue electronics data or digital electronic data format.
Although the term is usually associated with content recorded on a storage medium, recordings are not required for live broadcasting and online networking.
Any equipment used in the electronic communication process (e.g. television, radio, telephone, game console, handheld device) may also be considered electronic media.
