Marketers are working harder than every to capture our attention. A few years ago, a campaign promoting the remake of the King Kong movie put an enormous billboard cutout of King Kong climbing the side of a building in New York. If you sent a text message to a certain number, King Kong’s eyes would blink. Though the technology was rudimentary, this campaign created a lot of guerilla (not “gorilla”) buzz and thousands of passers-by stopped to briefly interact with the billboard.

When I got off Marta at the Candler Park station today, I saw a billboard for a new R&B compilation called “Platinum Tracks,” which is available exclusively at Target Stores. The billboard features an earphone jack, and I actually plugged in my headphones to hear a preview of the album.

While this billboard will no doubt create a lot of buzz, it goes a step further and actually demo’s the product. And the placement is perfect. Marta riders have a lot of time between trains, and iPods and portable CD players are ubiquitous, so there’s no shortage of people with headphones. The Edgewood Target store is only a 10 minute walk from the Candler Park station.

Great example of a billboard that captures our attention, and once it does, it actually has something valuable to share.
