Most important inventions since 1950 in the USA

Microwave (1945)

 A microwave oven, commonly referred to as a microwave, is a kitchen appliance that heats and cooks food by bombarding it with electromagnetic radiation. It was invented with a military purpose, but they discovered it heated things so by 1950s is started being used like we use today.

Airbag (1952)

An airbag is a vehicle safety device. It is an occupant restraint system consisting of a flexible fabric envelope or cushion designed to inflate rapidly during an automobile collision. It was developed by Dr Allen S Breed in 1967.

Snowboard (1965)

Snowboards are boards that are usually the width of one's foot longways, with the ability to glide on snow. It has been an Olympic game since 1998, but it started as a home-made table to enjoy snow.

Compact disc (1965)

Compact disc (CD) is a digital optical disc data storage format. The format was originally developed to store and play only sound recordings but was later adapted for storage of data (CD-ROM). American inventor James T. Russell has been credited with inventing the first system to record digital information.  Russell's patent application was first filed in 1966, and he was granted a patent in 1970. Following him, Sony and Philips licensed Russell's patents  in the 1980s.

Handheld calculators (1967)

In the early 1970s, the daily lives of people throughout the developed world were changed profoundly by the invention of Jack Kilby. It was a small electronic machine that could perform basic mathematical problems much more quickly and more accurately than they could be worked out on paper. Calculators expanded the math capabilities of everyone from high school students to businessmen.

Email (1971)

A local inter-user mail (Ray Tomlinson) program incorporating the experimental file transfer program, CPYNET, allowed the first networked electronic mail.

Mobile phone (1973)

It is a phone that can receive telephone calls over a radio link moving around the area. The first handheld cell phone was demonstrated by John F. Mitchell and Dr. Martin Cooper of Motorola.

Personal computers (1976)

Today’s personal computers are drastically different from the massive, hulking machines that emerged out of World War II. By the 1970s, technology had evolved to the point that individuals could purchase unassembled “microcomputers” and program them for fun, but these early PCs could not perform many of the useful tasks that today’s computers can.

Social media (2002)

One of the first social media in the world was Facebook; its creator was Mark Zuckerberg who now owns other important social media such as Whatsapp.

Segway (1997)

 It is a self-balancing personal transportation device with two wheels; can operate in any level pedestrian environment. It was introduced to public in 2001.
