Not Until

I am looking at the ridiculous pile of phone books I receive every year and it bugs me. Why in the world do we need 2 major producers of phone books? The two major phone books along with all those little local guide phone books - sheesh! That is a lot of wasted paper. In this digital age I am unsure why most of us even need one phonebook.
Why is the phone book not an opt-in experience?
Why are we letting the easy to fix things like this slip by while people are trying to do away with cheeseburgers?
