1903 On the initiative of Emperor Wilhelm II, the Allgemeine Elektricitäts-Gesellschaft (AEG) and Siemens and Halske AG jointly founded the Gesellschaft für drahtlose Telegraphie System Telefunken - better known as Telefunken. This was a political reaction to the developments in radio technology that were in progress in Great Britain.

Post-WWI: Telefunken engineers laid the foundation for the introduction of radio in Germany (1923).

1930s Telefunken was substantially involved in the development of electronic television.

1941 Siemens transferred its Telefunken shares to AEG.

From the beginning of the 1970s, technological change and competitive pressure led to the rapid decline of AEG, and its various holdings were gradually sold.
