This document discusses trends in internet usage in the United States. It notes that as of 2005, there were approximately 280 million internet users in the US, with 105 million using broadband connections and 70 million still using dial-up. It projects that broadband usage will continue growing while dial-up declines. The document also references a long tail distribution of book sales on Amazon, with a large number of less popular titles accounting for 29% of sales despite representing a much larger portion of Amazon's total inventory compared to top "hit" titles.
