Microwave oven

1947

The microwave oven was created by chance (see ‘Accidents of invention’), but despite its serendipitous origins, the first commercial microwave was sold in 1947, with the Raytheon Company releasing its Radarange unit. The Radarange was 1.8 metres (six feet) tall, weighed 340 kilograms (750 pounds) and cost $5,000 — over £33,800 ($51,000) by modern standards! Today, the microwave is a staple feature in most kitchens as a speedy means to cook our food.
