Electronic Media are media that use electronics or electromechanical energy for the audience to access the content. This is in contrast to print media which is created electronically but doesn't require electronics to access the information.

The primary electronic media sources are video recordings, audio recordings, multimedia presentations, slide presentations, CD-ROM and online content.

These day's the field Electronic Media is often divided into television and radio.

Electronic Media is very versatile, being used in journalism, marketing, education, science, engineering, fine art, music, commerce, entertainment, military and infrastructure.

Marketers use Electronic Media as a way of making their advertisement entertaining and purposeful. Video recordings of people using a particular product or in a certain location can give buyers a first hand look of a new product or a peaceful holiday location, they may be interested in investing in. Multimedia and slide presentations are being used more often with the increase of electronic media standards. These presentations are now being transmitted all over the world in just seconds, reaching more and more potential buyers.

Education systems are introducing electronic media resources into Schools, Tafe's and Universities to enable easy access to information from all over the world via the Internet, more entertaining presentations through PowerPoint's and slide shows and the ability to convert radio or television clips into files, accessible to everyone through computers.

This all seems easy enough to comprehend but it took approximately 230 years to get where we are today. Signal processing began in 1745 then fibre optics evolved from 1956-1970 and the completion of the Internet in 1996.

Engineers and computer programmers have found regular work over the the past two centuries and employment opportunities should continue to rise as demand for electronic media continues to grow.
