Whoops! These photos of ad agency Crispin Porter's Job Manager shows dates for Windows Phone ad campaigns as going "live" January 4th and 8th.
Crispin Porter Co-Chairman Alex Bogusky posted the shot to demonstrate CP's massive project status list, which clearly lists two ad campaigns, on January 4th and 8th, for "Windows Phone", first as "Windows Phone Q3 Media Refresh" and second as "09 Windows Phone Banners". So who knows what the actual timing for these ads will be, but its a safe bet that ads will be previewed at CES in some way. (Crispin Porter, by the way, was responsible for the Seinfeld Ad campaign).
