Marketing is how you go about promoting and selling a product. Any ad campaign is a type of marketing.Marketing has to do with making people aware of what you have to offer, whether it's updated software, a clearance sale, or ice-cold lemonade. If a commercial really makes you want to buy something, the marketing worked. Politicians use marketing in their campaigns to convince voters. Marketing is all about selling — and given how many ads there are everywhere you look, it’s probably one of the most powerful forces in the world whereas sales is income (at invoice values) received for goods and services over some given period of time.
