I saw an article on the web, but cannot now find it, that at first when GDR started broadcasting, they use System D, then at some point, I think sometime in 1960s, they switched to System B, but now I cannot find this link

BTW, System D was the original 625-line system. System B came about because Germany wanted to fit three channels into a 21 MHz band.
