Media as one of the channels to deliver a marketing message to your potential customers, is another great way. Advertising in a newspaper, magazine, television or radio can be quite effective. It all depends on what product you offer. And what edition do you use for advertising? The more the target audience reads a particular newspaper or listens to a particular radio station, the more response will be able to get your advertising message.
You can also use advertising articles, interviews or pre-releases. There are promotional articles that disguised as informational articles.
To track the effectiveness of, for example, the same advertising on different radio stations, you can use different phone numbers, in one ad you give one number, in another another number. It's the same with other media channels.
Advertising in the media can be quite effective, because the audience coverage is huge, if you release a mass product, it can work.
