This I Know

Big Marketing Lessons for Small Business

Now a Globe & Mail Bestseller!

Canada’s most famous adman spills a career’s worth of marketing secrets, so anyone can compete with the best in their business – whatever that business may be.

Big Companies spend a fortune marketing their wares and services. Can yours? Invariably people ask advertising veteran and CBC Radio host Terry O’Reilly one question more than any other: How does a little business that can’t afford a big-time marketing agency access high-level marketing thinking? 

After decades at the helm of an award-winning advertising company, and over a decade exploring the art and science of marketing for CBC Radio, O’Reilly delivers all the answers they--and anyone with something to sell--ever wanted to know. 

Following his bestselling Age of Persuasion, O’Reilly collects a lifetime of marketing wisdom into an indispensable guide to competing for your customer’s attention. From understanding what business you’re really in and foregoing the extra mile in favour of the extra inch, to the benefits of counter intuitive thinking and knowing an opportunity when you see one, This I Know will help anyone understand the fundamentals of good marketing strategy and building the relationships that turn good marketing into great results, no matter how big or small your budget.
