日本における電子レンジのデザイン変遷: 新聞記事と広告調査からみえる普及過程

The spread of microwave ovens in Japan was premised on the spread of refrigerators. Initially, manufacturers appealed that they could cook easily in a short time and tried to disseminate it. Next, it was advertised that real cooking can be done. However, sometimes it was accused of excessive advertisements which appealed that anything could be cooked. Although the main factor of popularization is price reduction, the penetration rate exceeded 90% in 1997 due to the development and spread of kitchenware and frozen foods. A unique design was born in the process of dissemination, but its main use became general and disappeared in the commoditization.
