In 1970, he co-hosted the Emmy Awards Show (from Carnegie Hall in New York) with Bill Cosby (from Century Plaza in Los Angeles). His most popular talk show was his ABC program, which ran from 1969 to 1974. From 1962 to 1992, The Tonight Show Starring Johnny Carson was arguably the most popular late-night variety and talk show. Unlike many contemporary shows that attempted to compete with Carson in the same timeslot but were quickly cancelled, Cavett managed to remain on the air for five years despite ABC being a smaller network with fewer affiliates than NBC at the time. Cavett earned a reputation as "the thinking man's talk show host" and received favorable reviews from critics. As a talk show host, Cavett has been noted for his ability to listen to his guests and engage them in intellectual conversation. Clive James described Cavett "as a true sophisticate with a daunting intellectual range" and "the most distinguished talk-show host in America." He is also known for his ability to remain calm and mediate between contentious guests as well as his resonant voice. His show often focused on controversial people or subjects, often pairing guests with opposing views on social or political issues, such as Jim Brown and Lester Maddox. On February 11, 1970, Cavett hosted a tribute to the life and works of Sir Noël Coward, who had just been knighted in December 1969. Coward appeared as a guest, along with Alfred Lunt, Lynn Fontanne, Tammy Grimes, and Brian Bedford, each of whom were enjoying a successful run on Broadway in the revival of Coward's play, Private Lives. In reviewing the show for The New York Times, television critic Jack Gould said, "The age of youth? Balder dash! The over‐70 set walked off yesterday morning with a television program that combined the engaging qualities of lightly recalled nostalgia, the sophisticated stiletto, and a demonstration of genuine affection that had more substance than adolescent wails on how love will save the world. Sir Noel Coward, Alfred Lunt and Lynn Fontanne, friends of a lifetime, met on Dick Cavett's show on the American Broadcasting Company network. They exchanged quips, pleasantries and thoughts about the theater with the beguiling charm of talented luminaries. Mr. Cavett was clearly overawed, and for once, the ad libs frequently went over his head. It was an enchanting show ... and the badinage was warm and delightful ...
