YouTube served its 500,000,000th Promoted Video view this week. Using Promoted Videos (available in your AdWords account), businesses can promote a video against search results on YouTube. But Promoted Videos offers a discovery component as well, allowing advertiser’s messages to be promoted against related content (BBQ grills shown against recipes for hamburgers) that someone may be viewing as they browse videos on YouTube. For more information on new product enhancements, please see the full story on the YouTube blog.
