1967 – Dishwashers and Microwaves
In 1967, Raytheon, the first microwave company, introduced their products to the general public. Before then, this handy cooking appliance was limited to the rich and powerful. But in the late 1960s, they were as common as refrigerators. Another item that popped up in American kitchens was the dishwasher, which made many housewives very happy because they no longer had to suffer washing dishes after slaving over a hot stove all day.
