The Z4 was arguably the world's first commercial digital computer, and is the oldest surviving programmable computer. [1]: 1028 It was designed, and manufactured by early computer scientist Konrad Zuse's company Zuse Apparatebau, for an order placed by Henschel & Son, in 1942; though only partially assembled in Berlin, then completed in Göttingen in the Third Reich in April 1945, [2] but not ...
The Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world's first working programmable, fully automatic digital computer. [3] The Z3 was built with 2,600 relays, implementing a 22-bit word length that operated at a clock frequency of about 5–10 Hz. [1] Program code was stored on ...
After that, production of slide projectors was transferred back to Germany so that they, too, could be marketed under the catch phrase "Made in Germany". The P801 slide projector was initially made by Silma in Italy, but its successor, as expected, was also made in Braunschweig. These products were manufactured in leased premises within Rollei ...

While, overall, Germany's ICT market is the fourth largest worldwide [3] and the largest in Europe, [4] high-speed internet is hardly seen in its more rural areas. [5]ICT stands for information and communication technologies, and includes any devices and systems utilized in digital technology and communication. [6]
2004: World first: adaptive 28 CS-2 digital flash unit with immediate correction button. 2005: Metz's in-house design of “made in Germany” LCD-TV sets (HDTV ready) are introduced for the first time, together with the new Slim TV product range with visibly reduced CRT housing depth.
The Z1 was a motor-driven mechanical computer designed by German inventor Konrad Zuse from 1936 to 1937, which he built in his parents' home from 1936 to 1938. [1] [2] It was a binary, electrically driven, mechanical calculator, with limited programmability, reading instructions from punched celluloid film.
