Nick: Two worlds of measurement: GRPs world vs 'internet world'. Nick: 'socialization' of brands: Nike+, rather than just sticking up a Facebook page. Ted: three issues-portability, personalisation, privacy. Ted: growth of privacy issues. Ted: tell stories, not things. Head of interactive for P+G:'maybe social media is just social', ie maybe it's not a place in which to advertise. Nick: planning approach has to shift from campaign-focused to recency-focused, since consumers are there all year round. Nick: cost per click should go away. Wants panel-based approach based on effect of ads (two groups: one who has seen the ads, one who hasnt-payment based on diffrerence in brand metrics). Ted: "looking at a 10 year renaissance in measurement". Ted: "this is one of the most exciting times to be in this industry ever".
