Electronic media, a term referring to any device or medium that uses electronics or electromechanical energy, allows users to access its content. Originating in the late 18th century, it began with the emergence of wire and transmission lines, leading to the invention of the telegraph, fax machine, and telephone in the 19th century. The 20th century brought about revolutionary progressions such as fiber optics, radio transmission, LED and LCD displays, and wireless communication. The evolution of signal processing and information storage was marked by the creation of capacitors, Morse code, electronic modulation, and digital encoding techniques. The diversity of electronic media formats increased with the introduction of vinyl records, digital audio files, and a range of video formats. Significant advancements were also made in audio and video recording technologies. The development of control panels, input devices, and game controllers enhanced interactivity[1]. Today, electronic media is indispensable in the realms of communication, entertainment, data transmission, and information storage.

Terms definitions
1. interactivity. The term interactivity refers to the mutual relationship between humans and technology, or among humans themselves, facilitated by information exchange. This principle is crucial in numerous areas such as human communication, computer science, web design, and artifact communication. It encompasses human interactions such as message exchange and interpretation of body language. In the technological sphere, interactivity denotes the way systems like computers react to human activities and tasks. For instance, a website may incorporate elements like hyperlinks and multimedia presentations to encourage user engagement. In the context of artifact communication, interactivity represents the connection between the user and the artifact's functionality. Thus, interactivity is a key element in fostering a dynamic information exchange in both human and technological interactions.
Electronic media (Wikipedia)

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.

A screenshot of a web page. The computers to store, transmit, and display the web page are electronic media. The web page is an electronic medium.
Graphical representations of electrical audio data. Electronic media uses either analog (red) or digital (blue) signal processing.

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.
