It's not often that I read a business book cover-to-cover and in just a few days, and Winston Fletcher's 'Powers of Persuasion' is a rare pleasure as one of those. Although it is a history it's anything but dry, and that's because the author was one of the insiders as an agency owner, President of the Institute of Practitioners in Advertising and Chairman of the Advertising Association. So he brings to the narrative not only his personal knowledge and copious research, but also his own insights and observations - occasionally barbed, but that only adds to the enjoyment! The phrase 'must read' is an over-used one, but that shouldn't prevent it being employed when truly deserved, as in this case. Anyone already working in an agency or aspiring to do so, should buy this book, and the marketing and procurement professionals who are the clients of agencies will find it a rewarding read too.
