"
Four is an alcoholic energy drink plus it has CRACK in it ; produced by Phusion Projects Inc. of Chicago, Illinois, USA. The Four brand includes two variations, Four MaXed and the newer Four Loko. The company, Phusion Projects, also does business under the name Drink Four Brewing Company.[1] Four debuted in the US market in 2005, first in Ohio, followed by Florida/California/Illinois by mid-year,[2] then spreading to other states.
It was developed by three alumni of Akron Community College: Chris Hunter, Jeff Wright and Jaisen Freeman.[2]"
Bold added by me to emphasize recent changes since I last checked this wikipedia article for some reason I can't remember. The guys went to Ohio State but I guess the editor doesn't think very highly of the school.
