Phonebooks: Why?

Phonebooks in the 21st century. Why do they persist? The other day, I was minding my own business. I walk outside and there is this white unmarked van. A bunch of goons get out, and start piling up phone books by the mailboxes. It is annoying enough all the junk mail I get. Why do we need a crate of 20 lb paper books as well? They (and the junk mail people) are doing nothing but delivering garbage to my doorstep. I don't want it, nobody does. We have this thing called the internet now. It is this amazing invention where you can type whatever it is you are looking for, and instantly, the machine finds it for you without having to kill any trees. Nobody uses phone books anymore. There is still a massive pile of them and it's been a couple of days. Nobody takes them, and they eventually get thrown out. I fail to see how this business is still profitable. As recently as 10 years ago, I could see a small business thinking that if they don't pay for the phone book ad, they will see less business. But in today's day and age, you just google locally. I can't remember the last time I looked in a phone book. I can't imagine that any small business would pay to be in one anymore unless the rates have gone down drastically. And even then, it would reduce their profitability drastically. So why do they still make them? There is only a small percentage of Old people that still use them. My parents don't, they know of this thing called google and have a tablet. I am not 100% certain (and don't care enough to look it up), but the local phone companies DON'T give you phone books anymore, unless you ask. Which is good for old people that don't use computers, and how it should be. I'm pretty sure these assholes delivering trash to me are third party companies like yellowbook. The local phone companies, in addition to being slowly diminished by cell phones, would rather charge you just $0.99 for directory assistance.
