Without a doubt the most influential marketing book I’ve read is Purple Cow by Seth Godin.
The book explains how today’s world has a shortage of available attention and as such, to be an effective brand, you must do things that are actually interesting to your customers.
Put another way, customers have tons of choice but small amount of attention, so creating products, promotions, etc that capture attention is the best way to sell products.
