If both contestants overbid, neither wins their showcase. Since 1974, the winning contestant wins both showcases if the bid is within a specified amount from the actual retail price of their own showcase without going over. Until 1998, the amount was less than $100. In 1998, it became the current $250 or less. The 2017 documentary Perfect Bid: The Contestant Who Knew Too Much tells the story of the only time a contestant bid the exact price of a showcase. Personnel Hosts Bob Barker began hosting The Price Is Right on September 4, 1972, and completed a 35-year tenure on June 15, 2007. Barker was hired as host while still hosting the stunt comedy show Truth or Consequences. His retirement coincided with his 50th year as a television host. His final show aired on June 15, 2007, and was repeated in primetime, leading into the network's coverage of the 34th Daytime Emmy Awards. In addition to hosting, Barker became Executive Producer of the show in March 1988 when Frank Wayne died and continued as such until his retirement, gaining significant creative control over the series between 2000 and his 2007 retirement.

Reruns of Barker's final season were aired throughout the summer from the Monday after his final show (June 18, 2007) until the Friday before Drew Carey's debut as host (October 12, 2007), when the season 35 finale was re-aired. During his time as host, Barker missed only one taping of four episodes; Dennis James, then hosting the syndicated nighttime version of the show, filled in for him on these shows in December 1974. In 1981, shortly after the death of his wife Dorothy Jo, Barker became an animal rights advocate and began signing off each episode with "Help control the pet population: have your pets spayed or neutered." After Barker's retirement, Carey continued the tradition with the same sign-off. On October 31, 2006, Barker announced that he would retire from the show at the end of season 35. In March 2007, CBS and FremantleMedia began a search for the next host of the show. Carey, who was hosting Power of 10 at the time, was chosen and, in a July 23, 2007, interview on Late Show with David Letterman, made the announcement. Carey's first show
