Real question; likely only for people who've lived in Germany for a substantial period of time:
How "big" / popular of a cultural phenomenon was Max Headroom, back at the time (1980sβ1990s)?
I kinda get the sense that it was a large thing, or at least larger than it was in other non-UK/US countries, based on the fact that there seem to be a lot of German-language books & memorabilia out there, which I don't see in other languages....
But perhaps that just represents the size of the market.
