Now that everything is run by computer and internet, yellowpage directories provided by the phone companies are very rarely used especially in rich countries. Even here at home, phone companies still distribute phone directories to the people around but it goes directly at the trash can. People here don’t find it very convenient and instead, they use People Search sites because it’s faster, simple, easy and all the infos are instantly available in less than 1 minute. Believe it or not, arier plan and even 3D view are even available. No wonder why more and more people prefer to do it online.
