Electronic media are media that use electronics or electromechanical energy for the end-user (audience) to access the content. This is in contrast to static media (mainly print media), which today are most often created electronically, but don't require electronics to be accessed by the end-user in the printed form. The primary electronic media sources familiar to the general public are better known as 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 analog electronic 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, desktop computer, game console, handheld device) may also be considered electronic media.
