text: Retirement Carson retired from show business on May 22, 1992, at age 66, when he stepped down as host of The Tonight Show. His farewell was a major media event, often emotional for Carson, his colleagues, and the audiences, and stretched over several nights. In tribute to Carson and his enormous influence, several networks that had late-night variety talk shows "went dark" for the entire hour he did the last show. After 13 tries, The Tonight Show finally won the Emmy for Outstanding Variety, Music or Comedy Series later that year, buoyed by the penultimate broadcast, which featured Johnny's final two guests: Robin Williams and Bette Midler.
  NBC gave the role of host to the show's then-current permanent guest host, Jay Leno. Leno and David Letterman were soon competing on separate networks.
  Post-retirement appearances
  At the end of his final Tonight Show episode, Carson indicated that he might, if so inspired, return with a new project. Instead, he chose to go into full retirement, rarely giving interviews and declining to participate in NBC's 75th-anniversary celebrations. He made an occasional cameo appearance, including voicing himself on the May 13, 1993, episode of The Simpsons ("Krusty Gets Kancelled"), telephoning David Letterman on a November 1993 episode of Late Show with David Letterman, and appearing in the 1993 NBC special Bob Hope: The First 90 Years.
