1950లో కనిబెట్టబడిన వీటిని ఇంకా వాడుతున్నాము...ఫోటోలు

Credit cards (1950). Diner’s Club introduced the first credit card in 1950.
Diet Soda (1952). The first diet soda, No-Cal, was introduced by the Kirsch Bottling in 1952. It’s inventors Hyman and Morris Kirsch created the sugar-free soda for hospitalized diabetic patients at the Jewish Sanitarium for Chronic Disease (now known as Kingsbrook Jewish Medical Center). In 1958, Royal Crown Cola introduced the second sugar-free soda, Diet Rite.
Roll-on deodorant (1952). Prior to the invention of Ban Roll-On, the most common deodorant was Everdry, a aluminum chloride solution that was applied with cotton swabs. Besides being messy and taking forever to dry, Everdry also had the nice side effect of eating through clothes.
Color television (1953). Color TV was the HD TV of its time; introduced in the U.S. in 1953, it took a while to catch on (more than a decade) due high prices and lack of color broadcasts. The first national color cast was the 1954 Tournament of Roses Parade.
Microwave oven (1954). The Raytheon Corporation produced the first microwaves for commercial use.
Automatic doors (1954). Inventors Dee Horton and Lew Hewitt created the sliding automatic door after witnessing the difficultly people had with opening swing doors in the wind.
3-Point seat belts. Volvo introduced the first three-point belt in 1959, prior and made them a standard item in the Volvo 122, that same year.
Ultrasound (1956). Ultrasounds were first used for clinical purposes in 1956 in Glasgow. But, it wouldn’t become common until the 1970s, when hospitals in Britain and the U.S. adopted it for use.
