At Davos, ad execs with Publicis and WPP Group have gotten into the buttoned-down equivalent of a barroom brawl over their shared passion, Internet advertising kingpin Google. WPP Group says Google is just using Publicis, Publicis says WPP Group is just jealous; one side effectively calls the other a slut, the other throws back "you're a luddite." Google CEO Eric Schmidt stays above the fray and traditionalists in the ad industry are reminded just how much gravity he has amassed. [Reuters via MediaBistro]
