Does the adult industry include things like strip clubs, physical stuff like condoms/vibrators, or dating sites/apps? I feel like a sufficiently broad definition probably encompasses a lot of money. If we’re talking specifically pornography, then I have no idea how big it is, but it certainly seems to be in a state of flux at the moment. I would love to see some additional resources describing cash flow in that industry and where things are currently moving.
