Millions of basketball fans will fill out NCAA tournament brackets this week and try to correctly predict the outcomes of every game. This is an inherently social time, and bracket games truly engage the masses. Participants love to brag about their picks across all audiences and age groups. So, we’ve chosen our favorite marketing campaigns that have incorporated brackets into their strategy:

The Alabama BBQ Bracket and “The Quest for the Best” – Alabama has a distinct and “tangy” BBQ flavor that stretches across the Southern state. The brackets cover North, South, Central and Gulf Coast BBQ favorites. Our pick? The Brick Pit in Mobile, Alabama.

The Census Bureau has launched Population Bracketology – it’s not very social, but you can test your city population knowledge and then share the results with the Census Bureau the next time they call or ring your doorbell.

MTV has launched “Musical March Madness” where you can vote on your favorite musicians and bands. The voting begins March 25, 2013!

So whether your into BBQ, the Fed, or MTV – you can get started with these brackets or build your own. Before you dive into building your own bracket – first think about how engaged your audience currently is. Happy Picking.
