Media buying is taking a commercial, or newspaper ad, or other sales message and getting it viewed by the intended audience. For example, an advertisement for Centrum Silver (vitamins for senior citizens) would not do well in Teen Beat magazine (a magazine for teens). A media buyer links the ad to the intended audience in order to make the ad effective. These ads are intended to sell a product and may be published on TV, online, newspapers or magazines. The media buyer negotiates price and placement of the ad for the advertisers.
