A couple of nuggets from a new Arbitron/Edison Media study (pdf) released today:

* Eight in 10 Americans have access to the Internet from any location. As of January 2005, 81% of consumers have access to the Internet from any location. This is a remarkable rise from the 50% penetration figure from just six years ago (January 1999).

* The number of people with a broadband Internet connection at home equals the number of people with a dial-up connection at home. In January 2001, only 12% of Americans with Internet access at home used a broadband connection. That figure has since quadrupled. Now, in January 2005, 48% of people with home Internet access have broadband, and 48% have dial-up service.
