The New York Times outlines the themes of this year's American Association of Advertising Agencies annual management conference, kicking off today in Bermuda: searching for more effective ways to reach elusive consumers; more accurately measuring adspend ROI; dealing with new technologies to deliver advertising; trying to figure out how to increase the diversity of their workforces to reflect the consumer population; fighting to convince clients that they shouldn't be treated like mere vendors or suppliers. Sounds like typical fare.
