From Sheffield to Chicago It's more than 80 years since Joseph Thornton opened his first sweet shop in Sheffield. Today there are over 150 Thornton's shops in Britain, but this is still a business in the traditional mould. Three generations of Thornton's sit on the board, they have avoided take overs, but can still beat the High Street giants at their own game. We go inside the factory and the shops to get a flavour of this family firm.
