This weekend, stuck in the land of dial-up, I paged through a print motorcycle magazine and compared the articles against the advertisments. All the ads were for gear, motorcycle shops, or vehicles to haul your motorcycles. Essentially, indistinguishable from the articles themselves. You can do the same with any reasonably niche dead tree publication.
The closer a publication moves to the right of the sketch above (going more niche) the more ads = information. The further to the left (going more general) the more ads are a distraction.
You’re already familiar with the Long Tail, so you already know this.

Sometimes, it just takes a moronically simple illustration to drive a point home.
Adding that image and this information to my next client pitch. 🙂
