Interesting story about VoIP (they term it Web Calls) being more popular than previously thought: Yahoo! News - Web Calls May Be More Popular Than Thought - Survey
Here's an excerpt:
Making cheap telephone calls over the Internet could be much more popular among consumers than previously estimated, leaving incumbent telecom service providers highly vulnerable, a survey revealed on Thursday.
Over 50 million western European consumers with a broadband Internet connection at home may use telephony software and special phones by 2008, British research group Analysys found.
"The impact on traditional telephony providers' revenues could reach 6.4 billion euros in 2008, representing 13 percent of the residential fixed-line voice market," said analyst Stephen Sale, adding this was a worst case scenario drawn up for operators who want to know how badly they can be hit.
Previous estimates forecast that up to five percent of revenues could be eaten away by Internet telephony.
