Coca-Cola Chok! Chok!

Mobile and creative thinking can come together to create really compelling marketing campaigns. In this example, Coca-Cola Hong Kong created a 'Chock Chok' mobile app that turned viewers smartphones into a remote control for their TV Ad.

To collect the Coca-Cola bottle caps that appeared on the TV screen, viewers had to swing their phones when the ad came on. Those who successfully managed to swing and collect were instantly rewarded with prizes that included cars, sports apparel, credit card spend value, travel coupons and movie tickets.

As a result the campaign was seen by 9 million people and the app got over 380,000 downloads.

For those wondering, the bottle cap collection was enabled through the audio signal of the ad which triggered the application and synced the user's motion with the ad. The accelerometer in the phone was also used to assess the quality of the motion. Together they were used to catch the bottle caps virtually.

However as far as I know, Honda in UK was the first to pioneer this kind of an interactive TV ad, even though it did not receive results like Coca-Cola.
