#21: The Yellow Pages
Kids these days have no idea about The Yellow Pages. Why would they? They have Google and Yelp at their fingertips to find all the answers they need. The concept of a giant yellow book full of phone numbers seems completely foreign to younger generations. Yet the famous Yellow Pages still exist.
You might even have one in your home! There is some mysterious force that has kept The Yellow Pages in business all these years. The miraculous part is that this giant tome is still completely free. Every once in a while, a new copy will appear on our driveways, free of charge. Thank you, The Yellow Pages, for staying in business to keep our doors propped open for yet another year.
