Taught was maybe a bad word choice. If you watch the promotional materials for Interstellar, you get a strong implication that they were the first to show what a black hole looks like, but that is not the case. People have picked up on that on that vibe and think that the tech behind the movie gave us the first pictures. There certainly was an evolution there, but it wasn't the start of it. No doubt Interstellar popularized and helped re-energizze discussions about black holes, especially since it came out just before LIGO started making discoveries, which propelled things even further.
