Microwave oven
Japan's Sharp Corporation began manufacturing microwave ovens in 1961. Between 1964 and 1966, Sharp introduced the first microwave oven with a turntable, a feature that promotes convenient even heating of food. In 1965, Raytheon acquired Amana. In 1967, they introduced the first popular home model, the countertop Radarange, at a price of US$495 ($ in dollars).
Jenn-Air
The original Jenn-Air Products Company was founded by Louis J. Jenn in Indianapolis, Indiana, in 1947, later becoming simply Jenn-Air. In the early years, the company was focused on manufacturing and marketing of industrial fans for use in a variety of commercial and industrial applications. In 1961, Jenn-Air's integration of one of these fans to a cook-top range led to the invention of the first self-ventilated downdraft range. The company expanded its product line to include many other kitchen appliances including microwave ovens, refrigerators, dishwashers, and small appliances such as mixers and blenders. Unfortunately Jenn Air quality control has suffered over time. Their glass cook tops consistently degrade (under the surface), oftentimes with only a few months of normal usage. No amount of cleaning or buffing will remedy the problem. As a result, customer demand has plummeted.
