I didn’t mean to downplay these new revelations. However, the role of the code-breaking success in defeating the Japanese and the Germans and facilitating the demise of the Soviet Union pales in comparison to the impact of the program discussed in the article (in my humble opinion).
In any event, with regard to when these intelligence operations occurred, according to the article (which I read) CryptoAG began during WWII, so there was almost half a (20th) century of intelligence collected by them. The formal sharing relationship between CryptoAG and the CIA and the BND began in 1970. Also, of the the three *mid-1900s* (not the early 1900s) intelligence coups I mentioned, the Venona project continued until 1980.
