n. manufacturing, trade; group of companies which produce a particular product; diligence, perseverance, tendency to work hard

For other uses of this term, see Industry (disambiguation) Industry (from Latin industrius, "diligent, industrious"), is the segment of economy concerned with production of goods. Industry began in its present form during the 1800s, aided by technological advances, and it has continued to develop to this day. Many developed countries (The U.K., The U.S. and Canada for example) and many developing/semi-developed countries (People's Republic of China, India etc.) depend significantly on industry. Industries, the countries they reside in, and the economies of those countries are interlinked in a complex web that may be hard to understand at first glance.
