Skype- The New International Comm Phenomenon

My friend Shauna went to Spain last year for a semester. So far away from friends and family, with only ten dollars on her card, she found a way to talk face to face for little or no fee. She explained to me how Skype works, for I have never gotten the chance to use it but would really like to. Her dad, whom used to live in Mexico, has left behind many family members and talking to them used to be a fortune. Now, fortunately for him and his family, Skype has allowed them to contact one another, so he gets to see his mom, dad and brothers on a some what daily basis. He went on to tell me how he even gets to watch bull fights and soccer games with them at the, something I found very different and interesting. Do other people use Skype to conctact friends or family over seas?
