Global Business: Steinway

For more than 150 years, Steinway and Sons have been building handmade pianos to please the ear of the most discerning musicians. Their sound fills concert halls around the world. Why? Is it simply because they're the best; the best marketed or is there another reason? Peter Day visits one of Steinway's two factories, in Astoria New York, to find out what gives this instrument its prized status in the concert world and ask if this once family owned firm can keep its place on the world stage.
