In 1945, in New York, a first batch of ballpoint pens was sold. The excitement at the same time was so great that the authorities had put up a police cordon! On this day, 10,000 pens for $12 apiece were sold - about the same amount received at the time the American worker gets for the entire working day.
However, in just two years of severe competition of the two largest manufacturers of pens cost of production ballpoint pens has decreased to such an extent that the price of a ballpoint pen has fallen by 24 times and was 50 cents.
It is interesting that the original core of the handle was folded in an accordion, in order to climb more ink. But straight rod was much easier and cheaper to produce, so it survived the evolutionary selection.
Ballpoint pen called the "ballpoint" in all countries: ballpoint pen - in English, bolígrafo - in Spanish, penna a sfera - in Italian, Kugelschreiber - in German. The only exception is Argentina, where the pen is called birami, in honor of Laszlo Biro, its inventor.
