Organizational and technological innovations in electricity around 1900 ushered in a new industrial revolution. Electrical lighting and motors changed the look of factories and cities. Centrally generated electricity allowed businesses to locate in new areas and become more efficient. These successes relied on the creation of large integrated systems, mostly run by corporations as state-regulated monopolies.
The success of electricity required a way to distribute it. Inventions such as insulated cables, transformers, and generators made the widespread distribution of electricity possible.
