Initially producing electrical equipment (such as light bulbs, motors and generators), the company soon became involved in AC electric transmission systems. In 1907 Peter Behrens was appointed as artistic consultant to AEG. This led to the creation of the company’s initial corporate identity, with products and advertising sharing common design features.
The company expanded in the first half of the 20th century, and is credited with a number of firsts and inventions in electrical engineering. During the same period it entered the automobile and airplane markets. Electrical equipment for railways was produced during this time, beginning a long history of supplying the German railways with electrical equipment.
After WWII, the company lost its businesses in the eastern part of Germany. After a merger in 1967 the company was renamed Allgemeine Elektricitäts-Gesellschaft AEG-Telefunken (from 1979 on only AEG-Telefunken). The company experienced financial difficulties during the 1970s, resulting in the sale of some assets. In 1983 the consumer electronics division Telefunken Fernsehn und Rundfunk GmbH was sold. In 1985 the company re-took the name AEG and the remainder of the company was acquired by Daimler-Benz; the parts that remained were primarily related to electric power distribution and electric motor technology. Under Daimler-Benz ownership, the former AEG companies eventually become part of the newly named Adtranz in 1995 and the AEG name was no longer used. Electrolux, which had already acquired the household subsidiary AEG Hausgeräte GmbH of AEG in 1994, now own the rights to use and license the brand.
