where did the term best boy come from
Best boy It's unclear why this term came to be used as a job title on film sets. As OED says, "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."
Boy band Arguably the most successful boy band manager from the U.S. was Lou Pearlman, who founded commercially successful acts such as the Backstreet Boys in 1993, NSYNC and LFO in 1995, O-Town in 2000, and US5 in 2005. Backstreet Boys and NSYNC became the two biggest boy bands in the late 1990s until the early 2000s, and Backstreet Boys went on to become the best selling boy band in history with over 130 million records sold.[10][11]
