Old Boy Network

An old boy network, or society (also old boys' club), can refer to social and business connections among former pupils of male-only private schools. British public school students were traditionally called "boys", thus graduated students are "old boys".

This can apply to the network between the graduates of a single school, also known as an old boy society and similar to an alumni association. It can also mean a network of social and business connections among the alumni of various prestigious schools. In popular language, old boy network or old boy society has come to be used in reference to the preservation of social elites in general; such connections within the British Civil Service formed a primary theme in the British Broadcasting Corporation's satirical comedy series Yes Minister. The familiar term 'It's not what you know, it's who you know' is associated with this tradition.
