The term business refers to activities or interests.
By extension the word became (as recently as the 18th century) synonymous
with "an individual commercial enterprise" and has also sometimes taken on
the meaning of "the nexus of commercial activities" or of "the
representatives of commercial activity".
Specifically, business can refer, collectively, to individual economic
entities. In some legal jurisdictions, such entities are regulated by law to
conduct operations on behalf of entrepreneurs. A manufacturing business is
commonly referred to as an industry: for example: the "entertainment
industry", or the "dairy industry", or the "fishing industry".
