I think the article is right on point, and I agree with what has been said in the thread so far.
I live and work in a major U.S. “regional” city, and recently performed in an Equity production of a big, splashy musical. We had full houses for all of our seven-week run. I’m the meantime, another local theatre that produces mostly non-musical, “serious” plays can barely get their small theater half-full.
Basically, unless it’s really amazing, has a built-in audience base (i.e. Shakespeare lovers, Harry Potter fans), or has a star actor, even people who generally like theater don’t go to straight plays that much anymore. If audiences want to see people sitting around talking about their feelings, societal issues, and philosophical ideas, they can turn on Netflix, HBO, etc. for a fraction of the price at home. It’s sad, but a reality that needs to be accepted by professional regional theatre administrators. They should assume that doing a newish, Pulitzer Prize-baiting play is going to be a major financial shortfall, and plan accordingly.
This was true prior to the digital age/post-pandemic era, but now it’s really true.
