Overview

Americans, including Internet users, relied mostly on TV for their news and the phone primarily for their communication needs in the days following the terror attacks on the World Trade Center in New York City and the Pentagon. But for many online Americans, the Internet played a useful supplemental role as a communications tool – through their use of email and instant messaging – and as a news source.

About the Survey

This report is based on the findings of a daily tracking survey on Americans' use of the Internet. The results in this report are based on data from telephone interviews conducted by Princeton Survey Research Associates between September 12, 2001 and September 13, 2001, among a sample of 1,226 adults, 18 and older.  Some 663 of them are Internet users. For results based on the total sample, one can say with 95% confidence that the error attributable to sampling is plus or minus 3 percentage points.  For results based Internet users, the margin of sampling error is plus or minus 4 percentage points.
