Crowdsourcing the new flavor in a product line is a great way to both interact with customers and ensure future sales, and the Kit Kat 'Choose a Chunky Champion' campaign is the latest from food brand Nestle on this front.

The Kit Kat 'Choose a Chunky Champion' campaign asks Kit Kat's Facebook fans to choose which of the four new Kit Kat Chunky flavors they like best and want to see produced for sale. The new flavors are double chocolate, white chocolate, peanut butter and orange, and voters can scan the campaign's advertisements with their smartphones and use the Blippar app (an augmented reality app) to choose the flavor they like best. The Kit Kat Chunky flavor that gets the most votes will become part of the Kit Kat Chunky product line for good. Further, Kit Kat will also award one voter each day with £100.
