Forecasted number of PCs using the Internet - IDC (International Data Corporation) Internet Commerce Market Model (February 2007, v11.1)
Mature markets include U.S., Canada, UK, France, Germany and Japan.
The penetration rate is based on an international sample and sourced by Millward Brown. The Emerging markets include China, S.Korea, Russia, India and Taiwan. The sampling error is +/-3.7% at the 95% confidence level. Emerging markets are surveyed every other wave and the percentages are carried over from the previous wave when the Emerging markets are not surveyed.
Total Player penetration is a calculation of the total number of PCs connected to the internet, multiplied by the weighted percentage of worldwide penetration from the Millward Brown study. This is an assumption made by Adobe.
