B&H seems to be pretty focused on techy things (and cameras of all sorts have always been techy things, though that corner of the tech market that has been declining for a long time now).
When they branch out to selling everything including fresh vegetables, motor oil, and computing services, then maybe they might be more comparable to the overgrown bookstore.
There used to be a much more distinct camera—and all rhe ancillary gear and consumables than there used to be. Though B&H still sells a ton of lighting and audio gear as well as printers and consumables for same.
They sell other stuff too but they’re still pretty photo and video-centric, laptops notwithstanding.
