We see the motivation and drive entrepreneurs have when they are creating a Company. They think they can create a product faster cheaper or more efficiently than their competitors and that's what makes them entrepreneurs.
We learn the marketing technique called word-of-mouth which shows how companies can use outlets like magazines and newspapers to spread and build awareness for their company or their products.
We see how Will Kellogg started his own company and used his own last name to boost the popularity of his own cereal brand and to make it more widely spread. Will knew that Kellogg was a prestigious last name so he took advantage of it.
