From bank machines to the Bank of England, from telephones to television, the inventions and innovations of Scots have, for better or worse, defined globalisation and changed the way we communicate. From the forgotten 18th-century Scottish banker whose financial experiments caused the first credit crunch, to the eccentric genius behind the first television transmission, the programme examines the extraodrinary stories of Scottish pioneers of commerce and communication and their phenomenal legacy. With contributions from Professor Tom Devine and John Logie Baird's grandson.
