Mass media advertising is advertising placed in mass media markets, where it will reach large numbers of potential consumers. This advertising tends to be expensive because of the sheer volume of impressions it provides, and it is necessary to design a campaign very carefully to have the best effect. Advertising firms specializing in mass media marketing are available for companies that do not want to handle their advertising needs internally. Most mass media outlets also have an advertising department to handle inquiries from customers interested in placing advertisements.
The mass media include Internet, television, radio, billboards, and other forms of mass communications.
