It is unclear why this term came to be used as a job title on film sets. According to the
Oxford English Dictionary, "It has been suggested that it originated as a term for a master's most able apprentice, or alternatively that it was transferred from earlier use for a member of a ship's crew, but confirmatory evidence for either of these theories appears to be lacking." The earliest known appearance of the phrase in print is 1931 from the
Albuquerque Journal: "Among the electricians ... the department head is the gaffer, his first assistant is the best boy." As the gaffer is sometimes credited as the chief lighting technician, the best boy electric is sometimes credited as the "assistant chief lighting technician". The title is accepted for use in credits by the BBC. The end credits of the 1982 comedy film
Airplane II: The Sequel named the Best Boy, then the next line was "Worst Boy", naming
Adolf Hitler in that position. Recently, some film crews have begun adopting gender-neutral terms for job titles, with one example being
lead electric as a replacement for the term "best boy" in the electrical department. In 2024, the
International Alliance of Theatrical Stage Employees has most recently adopted the terms
assistant chief lighting technician and
2nd company grip for the electric and grip departments, respectively. ==Usage outside English==
