The most novel feature was the way in which the pen could write on wet paper or underwater and American stores were quick to take advantage of this. Demonstrations were arranged in which swimmers and divers went to the bottom of glass tanks and gave graphic demonstrations of the new sensation to the watching public. Even though the new Biro pens were expensive they quickly became very popular indeed.

At first, the history of the Biro Company was punctuated by lawsuits as others tried to capitalise on an idea which, by the standards of most inventions, had become an overnight success. Later on the real benefits of mass production were used to good advantage and the price dropped quickly until it reached a few pence. They took over Swan, the fountain pen firm, but were themselves bought up by Bic, the French company.

But the Biros had started it all. Ballpoint pens are now the most popular form of writing instrument using ink and some two hundred million of them are produced each year in Britain alone. The tiny one-millimetre ball used for writing is now usually made of tungsten carbide rather than steel, but other than that little has needed to be changed.
