Jell-O and Twitter have teamed up to measure America's happiness with the Jell-O Pudding Face Mood Meter, which debuted as a website in late July 2011 and, as of July 28, is now an interactive real-time billboard in NYC. The website uses information from the popular social media site, reading how many smiley faces and how many frowns are typed into tweets, keeping track of America's mood. When the amount of 'frowny tweets' outweighs the smiling messages, the company gives away coupons for free pudding to random sad tweeters.

The Jell-O Pudding Face Mood Meter can be spotted at West Broadway and Grand, and is the perfect combination between branding and social media networking. The website and outdoor display use the same face of a man whose facial expression changes with the fluctuation in frown and smile percentages. As much as I love free pudding giveaways, I'm rooting for the smileys to reach an all-time high.
