More than anything else, I like Grant's books because he brings deep understanding to why we do stuff. His latest book makes the case for companies having a chief culture officer at the top table. He is not referring to the culture within the company. This is about trying to understand the culture around us so that the brand can stay relevant or become relevant. As always, Grant's words make sense. Unlike most business or marketing books, this is his own original thinking and insights. He weaves through the influence of various trends that surface through tv, movies, advertising, hip hop, talk shows etc. I particularly liked his analysis of Nike's "tag" TV ad in chapter 2.
