Coca-Cola has rolled out a Diet Coke campaign called 'Reward Your Mood' fronted by American actor Chace Crawford.
The campaign is led by an on-pack promotion which asks consumers to match their mood to one of those featured on the bottle, and then select it online via the Coke Unleashed website in order to recieve a specific reward.
The broader campaign features a range of online, out-of-home, point-of-sale and experiential executions and will run until 30 June 2012.
