Of course it's niche applications, but it is the Zeppelin NTs which is the biggest success story. They're used for tourism in Germany and advertising in the US (the Goodyear Blimps, which as the article points out are no longer blimps at all, but much larger Zeppelins).

Zeppelin Luftschiffstechnik have survived by being _very_ careful about the scale of their ambitions (i.e, it's very modest). They did deliver the three ships in the Goodyear fleet, though, as far as I know completely on schedule, which is rare in any project of that scale, let alone an airship project.

I still haven't written off Sergey Brin's project entirely, although it keeps getting delayed. Airlander I'm less optimistic about, but they did fly (and crash) their prototype and they're still around, so who knows.
