The second annual National Technology Scan conducted by Park Associates, a Dallas-based technology market research firm, have found that 29% of U.S. households (31 million homes) do not have Internet access and do not intend to subscribe to an Internet service over the next 12 months. The survey noted that 44% of these households say they are not interested in anything on the Internet, 22% say they cannot afford a computer or the cost of Internet service, 17% say they are not sure how to use it, 14% say using it at work meets their need and 3% said the Internet doesn"t reach their homes. The study also found U.S. broadband adoption grew to 52% over 2006, up from 42% in 2005. Roughly half of new subscribers converted from slower-speed, dial-up Internet access while the other half of households had no prior access.
