Cellcom, the leading Israeli mobile company, celebrated 3 million customers under the concept of ‘one big family’.Utilizing the internet's ability to create brand interaction, we created the world's largest digital jigsaw puzzle: a family portrait, made out of 3 million pieces, divided into 120,000 pictures of actual Cellcom subscribers (a special technological application was built for this project).Cellcom subscribers were invited to participate in the game and put the pieces together. Prizes were handed out to participants. In only five days internet users completed assembling the puzzle.
