An industry is generally any grouping of businesses that share a common method of generating profits, such as the "music industry", the "automobile industry", or the "cattle industry".
Industry in the second sense became a key sector of production in European and North American countries during the Industrial Revolution, which upset previous mercantile and feudal economies through many successive rapid advances in technology, such as the development of steam engines, power looms, and advances in large scale steel and coal production.
Following the Industrial Revolution, perhaps a third of the world's economic output is derived from manufacturing industries—more than agriculture's share.
If the product of an industry is of such a nature that its quality is substantially uniform and can be readily tested by purchasers, especially if the goods are such that they are ordinarily sold in large quantities, the competition between rival establishments must almost of necessity be a competition in price.
Industries manufacturing comparatively inexpensive articles for the retail trade, put them up in packages which become well known to customers; and those industries whose goods are sold under brands or trade-marks, or in some other form so that they are familiar to buyers, afford an example of competition of an entirely different kind.
The movement towards consolidation of industries in the United States began to be noticeable soon after the Civil War (1861-65), but it had not reached noteworthy proportions, excepting in connection with the railways, until within the last twenty years of the 19th century.
