Industry

In economics, different kinds of manufacturing and services are broken down into groups called industries. The word comes from a Latin word meaning "working diligently at a task". There are many different industries, like mining, farming and logging. The industrial revolution made new industries.
An industry produces goods or services which are of a common set of qualities and which are indistinguishable (called homogeneous, in economics). It uses standardised processes for production, mass production and divison of labor.
History.
Slavery.
Slavery, which is forcing people to make goods and services, has happened since ancient times throughout the world as a way to have low-cost production. It usually produces goods for which profit depends on economies of scale. International law has declared slavery illegal.
Industrial Revolution.
The industrial revolution (from the mid-18th century to the mid-19th century) saw the development and popularization of using machines to make goods instead of using hands. The industrial revolution played a role in the abolition of slavery in Europe and in North America.
