I don't want to disparage a reputable newspape like US Today, but the figure of 40% seem highly implausible.
Consider that only 34% of adults have access to the Internet (as of June 2012; source:
World Internet Users Statistics). And 1.2 billion people don't even have regular access to electricity.
I suspect the statistics were based on people in a particular country or region, or perhaps those who responded to an on-line survey and so by definition have Internet access (which is hardly a cross-section of the population). If so, they ought to make that clear.
