Analog communication is a communication method of conveying voice, data, image, signal or video information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that of a variable. It could be the transfer of an analog source signal using an analog modulation method such as FM or AM, or no modulation at all. Analog mass communication, in use earlier, was largely one way, from a source of message to a relatively large, heterogeneous, anonymous and passive audience. So, it was linear and static, neither interactive nor exploratory. It now refers to all non digitized media, such as print media, audio and video recordings, photography and films. So the contents are linear and static and are not dynamic.
