The magazine Hobby Magazin der Technik from Germany has in its issue number 15 from 18th of July 1983 an article about handheld games. They were just about to conquer the market in Germany. In the article you can read, that about 30‘000 to 60‘000 of these handhelds have been sold so far by the middle of 1983.

Unfortunately Nintendo Ggame&Watch is not mentioned in the article, instead there are pictures of two Multi Screen Games: Mickey&Donald and Green House.
