In 1995, Oprah hired former psychologist Phil McGraw's consulting firm to help her navigate the Texas beef trial. After her victory, Oprah invited the straight-talking "Dr. Phil" on her show in 1998, effectively launching the mustachioed self-help mogul's television career. He soon became a weekly guest, appearing Tuesdays as a "relationship and life strategy expert" to offer advice on parenting, weight loss, financial planning and romance. In 2002, Dr. Phil graduated to his own show, produced by Winfrey's Harpo Studios.
