Telefunken was a large German manufacturer of electronic equipment, with its headquarters in Ulm (Germany) and subsidaries all over the country, including Backnang (near Stuttgart). The company was active in many fields, ranging from domestic appliances (radio, television, etc.) to high-end radioequipment for the Department of Defense (DoD). Founded in 1903 as a joint venture between Siemens & Halske and AEG, the company has also traded as AEG Telefunken.

AEG was aqcuired by DASA and was later merged into EADS Racoms. The resulting company was subsequently sold to Cassidian and eventually to Hensoldt. Some parts are still based in Ulm, but have undergone many reorganisations in recent years. In 2004, the former Racoms 1 division was sold to the Israeli Elbit Systems conglomerate – that also holds Tadiran – and is now known as Telefunken Racoms. It is still based in Ulm and produces radio equipment for the German Army.

Officially, AEG Telefunken no longer exists as a company, but its name is used (under licence) by several companies in various fields, as it is considered a strong brand name. Telefunken Racoms (i.e. Elbit Systems) uses a red variant of the old Telefunken logo on its stationary and brochures.
