Skype tomorrow will reach a major milestone when it passes the 100 million registered users mark. Still a long way to go to catch up to McDonalds' "Billions Served", but Skype certainly is the fastest growing VoIP company. The company achieved this milestone in just two-and-a-half year’s time, and has nearly doubled in size from September 2005 when it had 54 million registered users.

"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. 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,"said Niklas Zennström, CEO and co-founder of Skype. “We owe the Skype community a debt of gratitude for helping us realize this exciting milestone and look forward to keep growing together."
