We knew Neuromarketing was new---but did you know how new? The Bristol Evening Post ran an article on June 9 listing the terms just added to the Collins dictionary (associated with Harper-Collins and similar to Webster's) and Neuromarketing was one of a handful of new terms just added! I tried searching online at Webster's to see if it was in there as well, with no luck yet, but it shouldn't be long before we see it there as well.
Here is the definition added by Collins: Neuromarketing: the process of researching the brain patterns of consumers to reveal their responses to particular advertisements and products before developing new advertising campaigns and branding techniques
I believe we are truly witnessing an emerging phenomenon that will continue to get noticed in a big way.
