The first of three programmes exploring the changing face of city life around the world.
The world's most powerful city is on a roll again, but in a unique way.
Professor Harvey Molotch of the London School of Economics returns to the city of his student days to see how the Big Apple's renaissance is reflected in its cleaned-up parks and public spaces, regenerated by local businesses and patrolled by private security guards.
Continues tomorrow at 11.25pm.
