The internet message service has made the world smaller since it first appeared in 2003. At a time when people travel the world more and more,Skype brings people together. Users can make free calls to each other anywhere in the world,and the high sound and video quality gives them the feeling that they are in a room with the people they are talking to. This is what is so attractive about Skype, and today over 300 million users make two billion minutes of calls a day.
