You are absolutely correct - I have no idea what ETV was like in the 70s, 80s and early 90s. Was it less government controlled during the Derg? Or is this post-1991 era?
Fair question. ETV was certainly more controlled during the Derg regime since it was an openly totalitarian government. That's not to say that this current regime doesn't have a tight grip on ETV although it sounds like you're already well aware of that.
