The Breeders' Cup World Championships is an annual series of Grade 1 Thoroughbred horse races, operated by Breeders' Cup Limited, a company formed in 1982. From its inception in 1984 through 2006, it was a single-day event; starting in 2007, it expanded to two days. All sites have been in the United States, except in 1996, when the races were at the Woodbine Racetrack in Canada. Attendance at this exciting two-day event can exceed 115,000. The Breeder's Cup has a distinct audience and a rather bold attitude – So the Propeller team members had a lot of fun creating these outrageously controversial and somewhat polarizing commercials.
