Why do I keep getting phone books?

Who still uses phone books?  I only have 2 phone books in my house and they are currently taped together and used as a booster seat when we have guests with kids.  I can't recall the last time I used a phone book to look up a number. So when a phone book arrives in my driveway I always ask why am I still getting one?

So why do I bring up this random topic?  I recently read an article "50 Activities Replaced by Technology" by Katie Lepi and I reflected back to many of these 50 items.  How many of these 50 items have been replaced by technology or when have you never used?
