Advertising is any paid form of communication from an identified sponsor or source that draws attention to ideas, goods, services or the sponsor itself. Most advertising is directed toward groups rather than individuals, and advertising is usually delivered through media such as television, radio, newspapers and, increasingly, the Internet. Ads are often measured in impressions (the number of times a consumer is exposed to an advertisement).
