As marketing point of view, yes we can create needs. the evolution of tooth brushes take for example. now you have a motorised tooth brush, sophisticated; who imagined this even before a brush was invented?
interaction with consumers is being made thru online surveys. however offline surveys should also be taken into account.
because the consumer behaviour of a online consumer who buys everything mostly thru credit card is totally different from a consumer viisting a superstore or a mall!
as most of the online buyers account for 75% from USA, then online survey should be relevant to US customers only!
