Second day at the Experiential Marketing Summit, second fantastic keynote.  The video above is one of several vitaminwater ads that was shown yesterday during a captivating presentation given by Glaceau chief marketing officer, Rohan Oza. Part of their "Try it." marketing campaign, this commercial demonstrates one element of the brand's Cinderella success story-- celebrity partners who are true fans of the brand.  Oza told stories of celebrities like 50 cent, Shaq, LeBron James and Kelly Clarkson seeking them out for face time.  The series of ads have personality-- funny, refreshing and right on brand.
