Advertising is a form of communication used to persuade audiences to take action regarding products, services, or ideas. Advertising messages are usually paid for by sponsors and viewed through various media such as television, radio, newspapers, magazines and websites. The history of advertising in India began with street side sellers and press advertisements, and has since expanded to include many modern media channels and techniques to reach large audiences. Advertising benefits consumers by informing them of products and prices, and benefits businesses by promoting sales and helping economies grow.
