I've met, lately, a really massive number of people who work in tech companies but say they work in "marketing" or "branding."

I'm not really sure what they do exactly, but I think it's to do with the amount of money in the ad tech business that drives profit for the likes of G, FB, etc. I guess decisions have to be made on product strategy, I suppose meetings with clients to discuss ad spend.

Question is doesn't that capital spend dry during recessionary times?
