Link to February 16 Network World article, "U.S. broadband adoption sees significant spike".
Excerpt: This is a big leap from 2007, when just over half of U.S. households reported having broadband connections. Additionally, broadband connections now account for roughly 92% of all U.S. household Internet connections, whereas they accounted for 82% of all U.S. household Internet connections in 2008.
But while overall broadband adoption has increased over the past two years, the report also found that critical gaps remain, particularly with regard to income, age and race. [Emphasis added.]
