There is a pretty clever way of marketing i met before, that is drawing a lottery and introduce the products as a prize. I agree with that using social media is a good way of marketing, but actually some medical devices are for old people and not all old people are familiar with facebook and twitter. Lottery marketing strategy is the kind of strategy works for all age groups. Firstly, sellers need to pick a place that has high flow of customers, and secondly they need to play a long game, and lots of customers will join in. Of course the game is not important, the important part is the product will be introduced as a prize and the function of the product will be introduced too. Sellers will introduce the product many times during the game. This kind of marketing makes customers easy to draw attention when sellers introduce the products.
