Ford Motor Co.'s Ford Division says its new Explorer Sport Trac is as "essential as gear gets" for active adventure-seekers in this new TV spot from J. Walter Thompson USA, Detroit. In the commercial, climbers scaling a mountain face call out a checklist of gear -- the last item is the sport-utility/pickup vehicle, shown hanging from cables below. The :30 broke last week on NBC and is part of the vehicle's estimated $30 million ad blitz. Copywriter: Dan Weber. Art director: Todd Ruthven. Ford eventually expects to sell as many as 100,000 of the trucks annually.
