Microsoft has been trying to appeal more and more to the youth demographic and have hired several high profile celebs to help achieve this. Now Pharrell Williams of The Neptunes has signed on to help push the software giants merchandise in a new deal announced earlier today. Pharrell, along with several other high profile celebs, will appear in several television and print ads with the slogan “Windows. Life without walls.”, being the new catchphrase of the ad campaign. Williams replaces Jerry Seinfeld as the spokesman for the company after Seinfeld’s ad’s were not getting much positive response. Neither Pharrell nor Microsoft has commented on the new deal but I’m sure Pharrell ain’t too mad at it. Look for the ads to be hitting the airwaves within the next two months.
