Since 2001, most Internet users say that they have continued reading the same amount of printed material, according to the USC Annenberg School Center for the Digital Future. Three-quarters said so in 2001, and 70% did in 2006.
But the number of Internet users saying they spend less time with offline printed materials rose from 19.3% in 2001 to 23.2% in 2006.
In a statement accompanying the findings, the USC Annenberg Center said Internet users "are using printed materials less often and are instead seeking out that information online, frequently from the online versions of the same sources. Everything in our work strongly suggests that this trend will increase significantly."
