I have worked in the advertising agency business for 25 years, and have searched high and low for a good book on how IMC is done. This book falls in the category of "one man's experience" and is not the end of my search. It's only minimally reflective of any reality I have experienced and is very basic. Plus, I'm not going to recommend a book that opens with the author's view of the vital importance of correct spelling, and then is filled with errors. He lost all credibility right there.
