Pioneers of VoIP services like Skype and Vonage were able to capture over 75% of the VoIP subscriber market in their initial years. Purchasing pattern across the world was consistently reflecting the same market share. However, over recent years, major internet service providers, primarily the Cable Companies, caught on and have developed and offered VoIP services to their Internet and Cable customers and the pendulum has swung the other way by 2008.
