Carey talked about the change in an interview with CBS This Morning, which aired in November 2019 (per YouTube). In it, he explained that when he started hosting "The Price Is Right," he used to be introduced as the "star" of the show. However, Carey feels that the contestants are the real stars of the show. "The only reason people watch the show is, they don't watch it for me. The main reason [is], they want to watch people going bonkers and having, like, the best day of their life," he said. Carey added that "The Price Is Right" contestants come from all walks of life, which only adds to the show's appeal.
This was just one change made to "The Price Is Right" after Drew Carey took over. According to the Denver Post, a year into Carey's tenure Mike Richards was brought in as executive producer to alter the show so that it would fit Carey's sensibility. Some of Richards' changes involved updating the prizes to include high-tech gadgets like iPads, and introducing vacations with video presentations rather than the familiar rotating set pieces.
Drew Carey might have only taken the "Price Is Right" gig so he could buy a soccer team, but he still puts a lot of work into his craft.
