iMedia interviewed Nissan's interactive marketing manager, Doug Simpson, ferreting out the major online elements Nissan continues to use with its ongoing roll-outs of new and updated car models. Lots of interactive stuff tends to come early, especially in pre-release mode, bowing to traditional media once a new model hits the streets. Simpson likes online's accountability, but noted its greatest weakness is the medium's lack of demonstrable linkage to offline sales. Simpson gives credit to agencies Sapient, OMD, Chiat-Day, Tequila and The Designory for the work.
