-Drucker emphasizes the fact that customers control the market and the product. As discussed in the class this past week, customers also control the demand process for products produced by companies. This did however make me think of the unique case of the Apple Ipad when it hit markets about three years ago. Customers did not really create the demand for the product, Apple created the demand for the Ipad and created new customers. This new innovation sparked a completely new line of products which is now demanded by the customer. However, in the beginning, Apple definitely created the demand for the product as customers did not really know what the product would be used for. I recall huge disappointments when first seeing the product, as many people thought that it was a product that would not be used by the customer (expected no customer demand. However, Apple was able to successfully create this demand even though initially people were very sceptical of the Ipad.
I found this very interesting article discussing the criticism received by Apple upon launching the Ipad. Customers were uncertain of the product initially, but demand was created.
