Strong Holiday Sales Boost Online Ads, Hiring

Improved retail sales show that Americans are willing to spend this holiday season, despite the sluggish economy. Shoppers on Black Friday spent on average of $399, 10 percent more than last year, while online sales on Cyber Monday surged by a third.

The holiday shopping spree not only bodes well for retailers, it's also a boon for workers looking for jobs in retail, since employers need to add more workers to keep pace.
