This has been in discussion since we got the concept of marketing. There are two school of thoughts one in favor of artificial need and other opposite. There was need of travelling so Ford come up with transport vehicles. now there was need of thirst but now you can't say that coke came up with carbonated drinks to full fill that need of thirst. You can full fill need of thirst by water but if you go for coke or Pepsi , That is your want you can not say that coke satisfies your thirst need. Now if you say about vehicle for transport it can be suzuki Liana but you Go for Toyota Camry now that is your want.We mix up need and want concept.Need is your basic necessity where is want is your wish to fulfill that need. Thirst by water is need and by Coke is want. so need is there marketer came up with different Choices to satisfy the need that is your want. Basic need (innate need) can't be created marketers discovers them and comes up with various alternatives to satisfy that need.
