I’m not sure if I’ve ever consciously bought something influenced by product placement, but I think Zazum has stumbled across something big. The Redwood City, CA startup is developing a mobile phone application that lists the products and clothing in your favorite television shows with links to external websites. So whether your thing is picking up some authentic Hank Moody shades or a piece in Blair and Serena’s infinite wardrobe, you’ll know where to get it, and of course be able to share with your friends on Facebook and Twitter. The verdict is TBD on the design and functionality, but I see this bumping up the value of product placement for advertisers.
