Isn't it way too early to tell what the effects of the campaign are? I for one had never heard of Old Spice before, still haven't actually seen their product (not so prevalent here), but I do look out for it when I go to buy deodarant, since I want to try it out.
Last time I "tried" Old Spice I got a rash. They make crappy deodorant. It's okay if you're used to it but if you switch prepare for the worst. For some reason I've found this to be more common with Old Spice rather than any other deodorant brand.
I wish we could go back to when nobody wore the stuff.
