Over the past decade, New York’s most populous marketplace has emerged from the shadow of Manhattan to become the most fashionable part of the largest city in the US. Helped by its cheaper rents compared with Manhattan, artists and hip young people have breathed new life into Brooklyn. This has established a creative culture and atmosphere that started in neighbourhoods before spreading out across the market.
    Mr. Demby and Mr. Butler’s idea was to create a street market to bring together Brooklyn’s newfound artistic culture and renewed community spirit. So eight years ago they rented out a large school yard and launched Brooklyn Flea, a street fair for salesmen selling antiques, crafts and food. Today it is the most popular street market in New York, [4]from April to November typically hosts 140 sellers every Saturday and Sunday across two outdoor locations. And from December to March it is held equally popular indoors.
