This post just seems tacky, complaining that because marketing textbooks don't mention his own concept of "permission marketing" that they're out of date.
Also complaining that Stewart making 20 million for text book is unreasonable, when he himself has made a substantial amount of money from writing educational books. Not to mention the 30 million he got for his games site Yoyodyne. Obviously that was completely reasonable.
True, but not referencing Google? I think a marketing 101 text probably needs to say something about the importance of having your website be discoverable in an internet search, or at the very least review how the commoditization of online advertising has led to a shift in the landscape.
Or maybe the textbook could focus on the important theory that needs to be covered, and leave keeping up to date with the newest fads up to the students and the professor teaching the course?
The theory is what gives the textbooks value. It's the timeless and constantly useful material that makes a textbook worth referring to decades later.
