For one thing, you&#x27;re conflating marketing to consumers and marketing to physicians. There is no value in patients demanding a drug because of some contentless, sunshine-and-rainbows advert. The value in drug companies talking to doctors is arguable, but I think that doctors&#x27; very limited free time in general would also be more effectively spent talking to independent analysts, or reading independent comparative research. See the National Institute for Clinical Excellence in the UK, or the Cochrane Centre.
