Advertising is a form of non-personal communication that pays for use of media to convey facts about goods, services, ideas, or institutions in an openly persuasive way. It aims to sell or secure favorable consideration. Fees for advertising are calculated based on factors like duration, frequency, rates, and dimensions. The objectives of advertising include introducing new products, increasing market share, securing dealers, familiarizing customers with brands, making more buyers accessible to salespeople, and increasing middlemen's knowledge of a company's products.
