A show isn't made of matter. If you pay for it, you can't take possession of it or resell it later. If you, the buyer, aren't available at the time that it is provided, you get nothing of value out of the deal. These are attributes of services like surgery or internet connectivity, not products like antibiotics and computers. ("Health care" and "tech" are too vague to be useful.)
Getting things for free is not, as you imply, a usual attribute of services.
