Marketing is the act of acquiring, satisfying and retaining customers. It is one of the primary components of business management and commerce.
Marketing is usually conducted by the seller, typically a retailer or manufacturer. Products can be marketed to other businesses (B2B) or directly to consumers (B2C). Sometimes tasks are contracted to dedicated marketing firms, like a media, market research, or advertising agency. Sometimes, a trade association or government agency (such as the Agricultural Marketing Service) advertises on behalf of an entire industry or locality, often a specific type of food (e.g. Got Milk?), food from a specific area, or a city or region as a tourism destination.
