The technology exists worldwide.
The history of technology is not only made of sophisticated innovations developed in advanced countries but in developing countries, also writes a daily basis to technological history, made of alternative uses and creative contributions of the techniques and devices varied.
We live in a world full of objects, whose stories go back several decades or centuries. Over time, technologies appear, become, die, are combined with each other, according to the uses given to them at all times.
Everywhere coexists new with the old, advanced with the traditional, to form a kind of contemporary palimpsest.
