After Google's search event this morning, TechCrunch TV got a chance to catch up with Marissa Mayer , Google's VP of Search Products and User Experience, in the demo pit. In our brief video interview, an enthusiastic Mayer touts Google Instant as a "whole new way to search,"a game changer akin to the introduction of power steering in the automotive industry. It's certainly a neat feature that optimizes the search experience, but the real question remains: how does Google Instant fundamentally change consumer behavior, and in turn SEO and Google's ad sales. Mayer was more tentative on this front. See video ahead. Bonus footage: After Mayer's interview, we also got a chance to talk to Steve Cheng, a product manager on Google's Mobile team, who gave us a quick demo on mobile Instant and discussed their upcoming rollout strategy.
