A little program called ‘Skype’ is revolutionising the way we communicate, offering the promise that “you can talk to anyone, anywhere for free. Forever.” The basic premise of Skype is enabling people to have a conversation via the internet, rather than across traditional phone lines. Once you have downloaded Skype free from the internet, you can ‘call’ other computers that also have Skype installed and, because it’s across the internet between computers, it doesn’t cost a cent.
