Some brokerage firms have developed into large companies, incorporating departments specialising in shipping's various sectors,
e.g. Dry Cargo Chartering, Tanker Chartering, Container Chartering, Sale & Purchase, Demolition, Futures and Research; other "
boutique" shipbroking firms concentrate on specific sectors of the shipping market. The principal shipping and shipbroking centres worldwide are London, New York City, Singapore, and Tokyo, as well as where many shipowners are based such as Oslo and Athens. Other places continue to develop in international shipping services, such as Hong Kong and Shanghai, Delhi and Mumbai, Copenhagen, Geneva, Genoa, Hamburg and Paris in Europe; and in North America, Connecticut, Houston, and Montreal are important shipbroking centres. Until the late 20th century, it was commonplace for shipbrokers to cover more than one discipline, although nowadays the vast majority of shipbrokers specialize in a specific sector. Like many financial services, historically shipbroking grew out of the
City coffee houses, becoming established at the
Baltic Exchange; among its most famous members being
Ernest Simpson, ex-husband of
The Duchess of Windsor (died 1972), and
Alderman the Lord Mountevans. The
Institute of Chartered Shipbrokers sets educational standards throughout the industry worldwide, whose
Fellows are accorded the privilege of using the post-nominal letters FICS. ==Sale and purchase==
