Last week I detailed a step-by-step system for using the money other companies are spending on advertising to make a little money of your own.  In 5 Steps To Making Money From the Top 50 Online Advertisers, I showed how you could use advertising spend to track trends and make predictions on what content to generate during the year to maximize your AdSense earnings.

ClickZ has posted more advertising statistics for you to add to the collection you started last week.  The December 2006 advertising spends by industry and ad type have been released by Nielsen//NetRatings.  This information can supplement and help you tweak the information you're using to plan content and website creation for the coming couple of months.

Print it out, grab your highlighters, and go to town.
