ORLANDO - Today (Wednesday) sees the crème de la crème of US media planning and buying- plus many from elsewhere on the globe - converge on the Magic Kingdom for the American Association of Advertising Agencies annual media conference.
    Titled Now, Soon and the Future, delegates will be treated to the intimate thoughts of media gurus ranging from ex-US vice president Al Gore (now chairman of TV channel Current) to Irwin Gotlieb of WPP Group's GroupM and Publicis media overlord Jack Klues.
    Prominent on the agenda are such matters as measuring ROI on commercials to the bewildering array of new media - among them cellphones, blogs, podcasts and videogames.
