The most complex node is the "global city", with links binding it to other cities having a direct and tangible effect on global socio-economic affairs. The term "global city", rather than "megacity", was popularized by sociologist Saskia Sassen in her 1991 work, "The Global City: New York, London, Tokyo". "World city", meaning a city heavily involved in global trade, appeared in the May 1886 description of Liverpool, by "The Illustrated London News". Patrick Geddes later used the term "world city" in 1915. More recently, the term has focused on a city's financial power and high technology infrastructure, with other factors becoming less relevant.
