Utterly fascinating stuff. To add to that, the programme
which ran for many years, centered around reports about the Eastern Bloc, especially human rights abuses that took place in those countries; it was considered to be something of an antidote, as it were, to
Der Schwarze Kanal
on East German TV. Reportedly, East German schools would also make pupils talk about what programmes they watched/draw the logos/clocks they saw on TV, as a way of finding out which families watched Western TV, and as such finding out which families were 'traitors' to the communist cause.
Incidentally, if anyone here is interested in East Germany, I wholeheartedly recommend you watch the film
Good Bye Lenin!
It's about a a devoted member of the Communist Party, who falls into a coma just before the November Revolution, and wakes up several months later, after the fall of the Berlin Wall. Her son is determined to convince her that nothing has changed, and thus, among other things, makes his own versions of various East German programmes, as a way of making out that all is hunky-dory in the communist paradise that is East Germany. An excellent film, IMO.
