Purple Cow If you look at a field of cows, guess what you'll see? The view will be dominated by black and white, with perhaps a few splotches of brown thrown in if you're lucky. Probably none of these will really grab your attention. But now imagine that you spot, against all odds, a Purple Cow in the field! It's safe to say you'd take notice, because a Purple Cow really is something remarkable! @Sour255 explains why traditional marketing no longer works, and why to be successful you need to build Purple Cows, remarkable products and services that stand out of the crowd.
