@flo I am not surprised that you had my post flaggged as you do seem to have an inability to realize/remember that I often do play “Devil’s Advocate” for the sake of prompting discussion, and also tend assume that the reader can make certain connections and thus only “tip the first domino” by bringing up the other end of the chain of logical progression. Sometimes what is clear to me isn’t clear to others though, and I occasionally forget that.
I said what I said about this being 2015 with the (apparently false) assumption that you would already know that the majority of adults in the US have a smartphone and thus no need for a phonebook. Now, I didn’t expect you to know the exact statistics as you don’t seem like the type of person who would even want to know that, but I thought you could at least take an informed guess based on the number of people you see every day who whip out a smartphone.
Now, the publishing and distribution of hardcopy books is far more expensive than posting on the internet, and that’s especially true of a thick tome like a phonebook. And since there are only so many pages, metropolitan areas would require literally an entire shelf to have the white pages for an entire metropolitan area. Seems kind of wasteful, which is why you rarely see white pages any more.
As for the Yellow Pages, well, you might want to read a little about their recent history before we get into that. But if you don’t feel like following that link, but the TL:DR version is that the Return On Investment of advertising in the Yellow Pages has declined to the point where fewer businesses even bother.
Why did the ROI decline? Fewer people were using the Yellow Pages.
Why were fewer people using the Yellow Pages? People were looking up businesses onthe internet instead.
Why were they using the internet instead of the phonebook? Because technology has advanced to where the internet is nearly ubuquitous; the majority of Americans carry it (or rather, a device that can access it wirelessly from nearly anywhere) in their pocket.
Why are people carrying the internet in their pocket? Because they can.
How can they? Technology has advanced to where that is possible, and society has taken advantage of that.
How did technology advance? It evolved over time. It’s now 2015, so technology will be more advanced than it was years ago.
Final question; does my original answer make sense now that I connected the dots?
