Google has made a deal  with Nestlé to use the name ‘KitKat’ for its next version of Android.

Despite the partnership, Google representatives were keen to point out that this was not a “money-changing-hands kind of deal”, although Nestle does plan to sell more than 50 million chocolate bars featuring the Android mascot on its wrapper. The KitKats will ship to 19 key markets including the UK, US, Brazil, India, Japan and Russia.

Another big announcement was made by Sunadar Pichai, Head of Android

As everybody finds it difficult to stay away from chocolate they decided to name the next version of Android after one of our favorite chocolate treats, Kitkat.
