Skype claims that it has hit the 100M subscriber mark. The VoIP company says it now has more than 100 million registered users of its free Internet-based calling service. This is more than two times the number of users the company had last year. Last year, Skype was bought by eBay in a deal that was worth between $2.5 billion and $4 billion.

"Skype has grown in leaps and bounds by making it simple for anyone across the world with an Internet connection to do something they could not do before - talk for as long as they like, to whoever they like for no cost," said Niklas Zennstrom, CEO and co-founder of Skype. "Passing 100 million registered users within such a short time reinforces how much people love how easy Skype makes it to call friends, family and colleagues all over the world for free."
