Let's look at a few of the inventions that make the modern world what it is today:
Antibiotics: A Scottish guy.
Internal Combustion engine: Belgian
Telephone: Scottish guy in Canada
Microchip: British guy
Television: A brit, a German, and a Scot invented the precursors, a pair of Russians invented the first television based on their work.
Computer: A brit if you count Babbage, Turing, or Flowers. A German if you go with Kuse.
Cars: a German
Satellites: Russians
Spaceship: Russians
Light Bulbs: Americans
Airplanes: Americans
On that list, the US has TWO things. Hell, the first personal computer was made by Italians. We often assume things are invented by Americans, when they aren't.
Not exactly a random sample, eh? Two can play this game.
The Lathe - America (Thomas Blanchard, 1822)
Electromagnetic Induction - America (Joseph Henry, 1831)
Morse Code - America (Sam Morse, 1838)
Telephone - America (Alexander Graham Bell, 1876)
Phonograph - America (Thomas Edison, 1877)
Light Bulb - America (Thomas Edison, 1878)
Process for economically producing Aluminum - America (Charles Martin Hall, 1886)
DC electric motor. (Frank Julian Sprague, 1886)
Airplane - America (Wright Bros, 1903)
Transistor - America (John Bardeen, 1947)
Hydraulic Fracking - America (Floyd Farrisand, 1947)
From the 1950's onward...
December 20, 1951: First use of nuclear power to produce electricity for households in Arco, Idaho
Solar Battery - Bell Telephone, 1954
The first PC used by one person and controlled by a keyboard, the IBM 610 was invented in 1957 by IBM.
Integrated circuit, America (1968 Jack Kilby)
1958-60: The LASER. 'merica
1969: The internet. America. (ARPANET first deployed via UCLA, SRI, UCSB, and The University of Utah.)
1972: The first video game console, used primarily for playing video games on a TV, is the Magnavox Odyssey.
1973: The first commercial graphical user interface was introduced in 1973 on the Xerox Alto. The modern GUI was later popularized by the Xerox Star and Apple Lisa.
1975: Altair 8800 was the spark that ignited the microcomputer revolution.
1973-75: The Internet protocol suite was developed by Vinton Cerf and Robert E. Kahn for the Defense Advanced Research Projects Agency (DARPA) ARPANET, creating the basis for the modern Internet.
Then in the 90's, we invented everything germane to the internet that we see today. Oh, and we invented the skyscraper.
