Inertia doesn't really seem like it would lead to 300% YoY growth...

OTOH, National Lampoon hasn't put out a magazine since 1998 or a film since 2015 (and that was a retrospective on the magazine).

I guess I'd agree that, in absolute terms, The Onion might be less of a cultural force than it was in 2005 (say), but part of that has to be that culture is a lot more long-tailed: music, movies, and TV aren't dominated by a handful of works either.
