29% Accessed Porn on Work Computers Last Month

Amid reports that Securities and Exchange Commission staffers accessed pornography while working as the economy crashed, the Nielson Company reports that more than 21 million Americans accessed adult websites on work computers in March.

That's 29 percent of working adults.

On average, users who looked at adult websites spent about an hour and 45 minutes on the sites in March, according to Nielson.

The company told CBS News Producer Jill Jackson that the average time per session workers spent looking at adult websites from work computers was 12 minutes and 38 seconds.

"Adult" sites were the fifth most accessed subcategory of sites accessed by workers (ranked by time spent per person), after member communities, online games, e-mail and instant messaging. It beat out classifieds/auctions and current events/global news, among other areas.
