Konosuke Matsushita was strongly aware of the importance of customer voice when developing products, and he constantly paid attention to what customers were desiring through initiatives such as offering prizes. This is compiled in a booklet called "What are Consumers of Electricity Desiring?" It can be said to be an early form of marketing. In addition, "One Story a Day" was a collection that instructed employees. In this way, from those days, communication between people was regarded as important, and this spirit continues as a tradition to this day.
