7. Printing Press
In 1454 the German goldsmith Johannes Gutenberg was the first to construct a press that comprised moveable metal type, which, when laid over ink, could print repeatedly onto paper. The introduction of computers in the 1950s revolutionized printing composition, with more and more steps in the print process being replaced by digital data. Now a days we have modern electronic printing presses in our homes and offices commonly known as “printers”.
8. Radio
A Russian, and the Italian-Irish inventor Guglielmo Marconi, saw the potential in this technology when they sent and received the first radio waves. Marconi sent the first transatlantic radio message (three dots for the letter “S”) in 1901. Since then Radio became an important part of our daily life, from listening to news bulletins to baseball matches, and even the invention of TV barely affected its significance.
