About National Microwave Oven Day
Microwave ovens first became available for home use in the 1960s. They quickly became popular because they offered a convenient and efficient way to cook food. Microwave ovens use microwaves, a type of electromagnetic radiation, to heat food quickly and evenly.
The first microwave ovens were large and expensive, but as technology improved, the price of microwave ovens dropped and they became more compact. By the 1970s, microwave ovens were becoming increasingly common in households across the United States and other developed countries.
