It is thanks to the creativity and intelligence of these men that today the telephone, the ballpoint pen, the electric light bulb, but also paper, steel, plastic, and of course the television exist. It is to these men that this episode is dedicated, many are known and some celebrated, such as Edison, Watt, Meucci and Marconi. We don't even know the names of others. In these two thousand years an endless number of inventions, small and large, have gradually changed the life of humanity, building the world we know today.
