VoIP Weekly reports that 40% of international phone calls are now carried by VoIP services, up from 2-3% in 2000. The article also states that VoIP has killed the calling card market. College kids have been a key demographic for that market, and apparently tech savvy youth are very comfortable using free services like FreeWorld Dialup and Skype to make phone calls. It's also a boon for parents of college kids who may have been buying some of those calling cards. The article also expects the wireline (traditional) phone industry to see a 40% drop in revenue by 2008 as more and more customers move to VoIP services.
