At CES last week Josh Silverman, Skype’s CEO mentioned that Skype’s international voice traffic went up 75% in 2009. This has now been approximately confirmed by Telegeography, which now puts Skype’s share of international voice traffic at 13%, up from 8% in 2008. That’s an increase of over 60% year on year.
Josh Silverman also mentioned that Skype was being downloaded at a rate of well over 300,000 downloads per day. Yes, per day. This number matches CKIPE’s observation that Skype added 2.5 million new users in the 11 days after Christmas 2009.
