Thought this was a pretty interesting book, and covers quite a lot of content. I'd probably recommend reading the likes of Byron Sharp, Peter Field, and Les Binet before tackling this book. I'd say this is less of an introduction to media and marketing, but for someone with a few years of experience.
I found the chapters on how advertising works, the evolution of media buying, the attention economy, and buying the best impression super insightful. More so the attention economy and buying the best impression. Quite new to my thinking, but worthwhile going away and looking into this area a bit more. It was great to hear the author's opinion on what the future good hold in regarding measuring quality impressions, through attention measurement.
It was also refreshing to hear a slight critique of the industry, from the murky waters of programmatic advertising to understanding that the internet is full of bot farms that take advantage of this non-transparent ecosystem.
If you've got a few years of media under your belt, give this book a shot. I'm sure you'll learn something new.
