A new study commissioned by the U.S. found that only 1 percent of Web pages contain sexually explicit material. The days that porn was the king of the web are clearly gone.
That study was described in the San Jose Mercury News and was based on search data that Google was forced to turn over to the Feds earlier this year. (The Justice Department's initial request was far broader.)
The analysis was performed by Philip B. Stark, a professor of statistics at the University of California-Berkeley, and is part of the Justice Department's legal defense of the Child Online Protection Act. The ACLU has sued to overturn the law, and a trial is currently underway in federal district court in Philadelphia.
