Do you remember the Yellow Pages? The huge yellow book that had more information that you knew what to do with... yea, that one. But then ask yourself this, "When was the last time I actually looked at it?"
The Yellow Pages, just like many other things, is becoming obsolete. It once was a great place to advertise your business, but not so much anymore. Other bigger and better ways to market a business came about, like the Internet and search engine optimization, for example.
