What is the difference between a world city and a global city?

Question by Heidi: What is the difference between a world city and a global city?

My textbook (A Sociology of Globalization by Saskia Sassen) says that most global cities are also world cities, but some are not world cities in the full sense of the term. It also says that world cities refer to a type of city that has been seen over the centuries, particularly in a lot earlier periods in Asia or European colonial centers.

I still don't get what the difference is. When I looked it up online, Wikipedia said that they are the same thing, but I need to know the difference.

if you read this article on mega cities then 'world cities' is the term that used to apply to the mega cities.

However with the increasing focus on information, the top mega cities have lost their productive role(making consumer goods) and are now the key cities, the global cities,New York, London. because their central role is as 'information hubs'

However it seems to be important not to get too caught up on seeing these two terms as completely different, -there are major overlaps between these defintions...
