Skype is the most popular voice communication service in the world. Skype is changing how people communicate with the integration of voice and Instant Messaging (IM) into one application. Talk when you want and type when you want, and switch between the two as you wish, seamlessly.
Skype has broken many barriers to communication. While in the past you needed to take particular care of the minutes and seconds you spend speaking on international calls, you no longer need to bother about that now. If you use Skype for computer to computer communication, you pay nothing more than the monthly internet service.
