Peter Day's World of Business

How have private businesses fared in Greece since the crisis began? The economy has shrunk by nearly a third and unemployment has soared. So what have companies had to do to survive? And have any managed to actually thrive? Louise Cooper meets hopeful entrepreneurs, embattled importers, and a few small companies going underground in a bid to avoid rising costs and disappearing demand. Can Greece ever return to growth? Producer: Rosamund Jones.
