In a letter to JWT headquarters in New York, Ford Motor said: "The terms stated in your letter ... are satisfactory and are hereby accepted ... with the understanding that Ford ... may at any time terminate the arrangement by written or verbal notice to your company. We trust that the arrangement ... will prove to be mutually satisfactory."
The agreement was signed by Ford purchasing manager J. Walter Thompson, who just happened to have the same name as the agency.
In the subsequent decades, JWT helped Ford launch many nameplates, including the Thunderbird, Mustang, Pinto, Taurus, Explorer, Ranger and Escort.
The first JWT campaign for Ford began in the winter of 1943-44. One ad showed a giant crystal ball with the caption, "There's a Ford in your future." Ad Age, an affiliate of Automotive News, said the slogan was intended "to reflect, at least, partial peace and the lifting of restraints and restrictions in civilian life" and also was "attuned" to "a quickened eagerness to own new cars." A similar ad debuted in 1945, showing a long, winding road in the familiar crystal ball captioned, "You'll go high, wide and handsome ... There's a Ford in your future." Ryan said the campaign teased the new cars that would be produced as the automaker switched from wartime production as the "arsenal of democracy" back to passenger cars.
