Sony’s first product was an electric rice cooker.
The first ever automated rice cooker that went on sale was made by Toshiba, who spent 5 years manufacturing it. However, one of the more primitive versions that never became available to public consumption was made by none other than Sony.
Sony’s first product was an electric rice cooker in the late 1940s. The electric rice cooker, made by merely interlocking aluminium electrodes which were connected to the bottom of a wooden tub, was a primitive product.
It used “interlocking aluminum electrodes” on the bottom of the wooden tub, which was constructed in a simple and mostly primitive way. Without the fancy technology we know now, the product did not consistently make tasty rice. It relied too much on the weight of the rice as well as the amount of water to cook evenly. Thus, this crude rice cooker model never became available for public consumption.
