The Top 50 Inventions of the Past 50 Years

Published in the December 2005 issue.

1955--TV REMOTE CONTROL
It marks the official end of humanity's struggle for survival and the beginning of its quest for a really relaxing afternoon. The first wireless remote, designed by Zenith's Eugene Polley, is essentially a flashlight. When Zenith discovers that direct sunlight also can change channels on the remote-receptive TVs, the company comes out with a model that uses ultrasound; it lasts into the 1980s, to the chagrin of many a family dog. The industry then switches to infrared.

1955--MICROWAVE OVEN
In 1945 Raytheon's Percy Spencer stands in front of a magnetron (the power tube of radar) and feels a candy bar start to melt in his pocket: He is intrigued. When he places popcorn kernels in front of the magnetron, the kernels explode all over the lab. Ten years later Spencer patents a "radar range" that cooks with high-frequency radio waves; that same year, the Tappan Stove Co. introduces the first home microwave model.

1957--BIRTH-CONTROL PILL
Enovid, a drug the FDA approves for menstrual disorders, comes with a warning: The mixture of synthetic progesterone and estrogen also prevents ovulation. Two years later, more than half a million American women are taking Enovid--and not all of them have cramps. In 1960 the FDA approves Enovid for use as the first oral contraceptive.

1958--JET AIRLINER
The Boeing 707-120 debuts as the world's first successful commercial jet airliner, ushering in the era of accessible mass air travel. The four-engine plane carries 181 passengers and cruises at 600 mph for up to 5280 miles on a full tank. The first commercial jet flight takes off from New York and lands in Paris; domestic service soon connects New York and Los Angeles.
