Data and Audience
Media channel refers to the specific outlet used to convey an advertising message to an intented audience. A newspaper is a media channel, as is television or radio. Media channels are often chosen by marketers based on a desired end result. If your product has a very specific audience, for example you make an essential widget used in open heart surgeries, then you probably wouldn’t advertise it on television. You might choose a targeted medical journal as the best media channel for your advertising.
