Of all the various telecommunications services in existence today, the one most used is the telephone. The impact of the telephone has been described as both positive and negative. On the negative side, wars are waged more easily, the scope of human conflict has been extended along telephone lines, and the multi-generational household has been broken up. On the other hand, lives have been saved through links to emergency services. The modern city, through telephonic connections, has created an increase in the speed and ease with which information transition takes place. Without the telephone the world would not be where it is at today. The telephone has aided in broadening communities, and allowing families to move apart yet stick together. With the invention of the telephone people were not only able to communicate better bet they were able to communicate more.
