Have you ever really thought about how things change over time. We see it every day, but we never realized when it happened. Our grandparents saw the radio gain a picture tube to become a TV. Our Parents witnessed that black and white TV coming to life with color. I can personally say I was amazed as a teenager to see a phone leave the wall and become wireless. Stop for a second, when the phone became mobile there was still a need for a paper phone book. Unfortunately, that phone book was never around when you needed it!
