first recorded 20th c.
The phrase originates from the 1930 historical satire 1066 and All That, written by W. C. Sellar and R. J. Yeatman. The authors employed the term to categorise historical events into a binary system of moral convenience, later seeing the expression adopted and further popularised through hacker culture.
