Walkers Crisps

Has anyone else noticed the recent re-design of the Walkers crisps packet. I know it's a boring subject but it really got me thinking about how a simple change to a design can change consumer behaviour. Working in a bar this summer there hasn't been anything for me to eat during me shift except Walkers crisps. Until recently i never ate them thinking they were too unhealthy to stuff my face with, but being such a porn to things such as advertising and aesthetics i've starting eating the odd bag (or two), and it's all down to the typography used on the packet cover. The old font used to tell us the flavour was bold and quite a heavy font. However they've now changed it to a much lighter font not too dissimilar to the font used on 'light' versions of the snack. I wonder if Walkers knew what they were doing, a clever piece of re-design making people think they are eating a lighter snack. Are they trying to save themselves in a market where health food reigns supreme?
