21st Century Fox (NASDAQ: FOX) (NASDAQ: FOXA) recently announced that it will start offering advertisers deals based on targeted consumer data instead of traditional Nielsen (NYSE: NLSN) ratings. Speaking to Variety, Fox ad sales chief Toby Byrne claims that by using the new tools, “advertisers will be able to identify and buy against audience segments — ranging from movie goers to luxury car buyers to first time car buyers to frequent fast food customers.” The announcement comes just weeks before TV networks start selling the bulk of their ad inventories for the upcoming season.
