Skype is probably the best video and voice chat program for Windows PC. It has the ability to maintain high audio and video quality even on a low-speed Internet connection. You get a variety of emoticons and video clips (called Mojis) to express your emotions; these Mojis are updated regularly with each version of Skype. Hence, you get new clips to share with your friends. Sending photos and videos is quite easy in Skype; you simply have to drag and drop them to its interface.
