The adult toy industry has an appetite for research. It's a curious thing, but it makes sense when you consider that they're in the business of selling products that have been traditionally taboo and under-researched (at least by academics). They want to know what kind of eco-friendly app vibrators people are buying, why they're buying them and how often their customers use their products.They collect this information in a number of ways: surveys sent out through email or snail mail; online questionnaires; interviews with store owners or employees; focus groups--even ethnographic studies where researchers go into stores as customers themselves! This last method can be especially revealing because it allows researchers to observe how customers interact with staff members and other shoppers while shopping for sex toys.
