I don’t really blog about advertising or marketing, though it seems to be one the most popular blogging subjects. I usually read Iain’s Crackunit for witty insights into the digital arena too.
But Seth Stevenson’s There Are 12 Kinds of Ads in the World is a great analysis of TV advertising genres along with some classic spots (mainly courtesy of the world’s video archive, YouTube). You’ll end up playing spot-the-format from now on.
It reminded me a great deal of George Polti’s 36 Dramatic Situations, which still remains a classic foundation of many a plotline, which is as good a place as any to start if you’re thinking of writing fiction, by the way.
