The word “evangelize” is said to come from the ancient Koine Greek language. Back in 300 B.C. it meant, roughly, “to proclaim.” Later, evangelists were known as people who spread religious gospel.

I define consumer evangelists as customers whose support for your products borders on religious. They are passionate for your devices; they are your public defenders; they are in love with your products (not like, love); they buy just about everything you make — or at least, they want to.

Most critically, they are communicators: they are foundation of your word-of-mouth effort. They tell anyone who will listen about why they are excited about your product. On the consumer electronics mountain, evangelists are the summit. There is no higher achievement.
