Well, the "traditional" greek system is generally viewed as the members of the North-American Interfraternity Council and the National Panhellenic Council. (The "white" fraternities and sororities). Of the members of the NPC, none were founded after 1917. The average date of founding appears to be about 1890. See
http://web.library.uiuc.edu/ahx/npc/ for more info. The years on the Fraternities stretch back farther. In both cases, most of the groups which started in the 20th century which have joined the two councils are the ones started by Jewish Students who could not be admitted to other greeks.
