Marketing is literally customer/product (market) identification and all the activity required to produce and deliver the product to customers. Business. Did you mean advertising?
Motte and bailey. Marketing is what you say on paper, but nothing like it in practice.
(And people have been giving me identical response with "advertising" in place of "marketing" for years now, so I'll say yes to both; the terms are effectively interchangeable in both motte and bailey cases.)
