Kodi Foster, Senoir Vice President Data Strategy, Viacom, is watching the media ecosystem carefully and is seeing some trends that could spell disaster for media companies. His talk at the recent PSFK Conference was a lesson in caution. For one thing, he believes that we are marketing to the wrong targets. Further, we may be coming to the wrong conclusions on the data we are capturing because the data itself is skewed, collected in echo chambers of like voices. Tread carefully, he warned, lest you be led astray.
