Johnny Carson is best known as America’s late-night king of comedy. For 30 years he hosted NBC television’s The Tonight Show; his topical monologues, irreverent characters, comical double takes, and frivolous sketches entertained more people than any other performer in history. His late-night arena provided plugs for untold books, films, and products; created a springboard to stardom for an infinite number of new performers; and more than occasionally offered a secure refuge for aging legends.

Carson began performing professionally at the age of 14 as a magician-comic, “The Great Carsoni,” for the local Rotary Club in his hometown of Norfolk, Nebraska. After a two-year stint as a Navy ensign during World War II and four years as a radio-drama major at the University of Nebraska, he plunged headfirst into the world of broadcasting as a radio announcer/disc jockey. When WOW in Omaha began television operations in 1949, Carson was there to host his first video program, The Squirrel’s Nest, a daily early-afternoon show. The young performer told jokes, conducted humorous interviews, and staged various skits with wacky comic characters and premises. Squirrel’s Nest gave Carson the opportunity to develop a good portion of his public persona and adjust his performance style to the intimate visual medium.

Relocating to Hollywood in the early 1950s, Carson’s television career took a step forward with his weekly low-budget series, Carson’s Cellar, on CBS’s KNXT. Performing monologues and satirical sketches reminiscent of his later work, Carson attracted the attention of such stars as Fred Allen, Groucho Marx, and Red Skelton—all of whom dropped by to appear on the local show at no charge. Based on his work with Carson’s Cellar, a more sophisticated Johnny Carson Show was created for regional broadcasts in the western United States. This program proved unsuccessful, and Carson subsequently began work for The Red Skelton Show as a writer.

Casting about for new on-air opportunities, Carson’s first prime-time network television exposure happened in May 1954, as host of the short-lived quiz show Earn Your Vacation. Fortunately, working for Skelton provided more of a career boost. When Skelton was injured during a show rehearsal, the young Carson was thrust instantly into the limelight as substitute host. On the strength of this appearance, CBS created a new prime-time Johnny Carson Show, a traditional potpourri of comedy, music, dance, skits, and monologues. Working through seven writers and eight directors in 39 weeks, the troubled show left the air because of poor ratings.

As quizmaster of the ABC-TV daytime show Who Do You Trust? in 1957, Carson’s career again took an upward turn. This highly rated daytime entry allowed Carson to display his engaging personality and quick wit through five years of continual give-and-take with a wide variety of guests. During this time, he also worked at extending his reputation and base of experience by appearing on a number of television musical variety shows and game shows, on Broadway, and as a guest actor in live television plays. Most importantly, Carson’s successes brought him offers to substitute for Jack Paar as guest host on The Tonight Show and ultimately to replace Paar when the temperamental emcee retired.

On October 1, 1962, Carson broadcast his first Tonight Show as permanent host. Less excitable and emotional than his predecessor, Carson’s relaxed pace, more casual interviewing style, impeccable timing, and ability to play straight man for other guests proved instantly popular with his viewing audience. Comparing differences between Paar and Carson, Time magazine reported on May 28, 1965, that “Paar’s emotionalism had made the show the biggest sleep stopper since caffeine. By contrast, Carson came on like pure Sanka. But soon his low-key, affable humor began to prove addictive. Paar generated new interest, but Carson is watched.”

Within four months of assuming the Tonight Show reins, Carson surpassed Paar’s old record night-time ratings by nearly a half million viewers, adding approximately 20 stations to the NBC network—this despite heavy CBS competition from former Tonight Show host Steve Allen. Incredibly, over a 15-year period, with continual competitive threats from CBS and ABC, The Tonight Show doubled its audience. Observed Kenneth Tynan in his New Yorker portrait of Carson on February 20, 1978, this was “a feat that, in its blend of staying power and mounting popularity, is without precedent in the history of television.”

Despite occasional contract squabbles, criticism over his numerous days off, marital conflicts, and assorted family problems, Carson continued to outdistance his competition for an additional 15 years. Without losing his timing, his unpredictability, or his perfectionist work ethic, for 30 years he kept his finger on the pulse of mainstream America’s moods, attitudes, and concerns. Combining his verbal dexterity with a well-stocked supply of facial expressions and gestures, he became the acknowledged master at lampooning the pretentious, salvaging the boring, or sharpening a nervous guest’s performance for maximum effect.

Through the years, Carson hosted a number of network television specials, including the Academy Awards and Emmy Awards, and performed stand-up comedy at the top hotels in Las Vegas. But it was The Tonight Show that guaranteed his place in American history. For 30 years, he entered U.S. homes to provide commentary on the day’s news, to help determine the next day’s conversational agenda, and, of course, to entertain. Over time, his mild-mannered, Midwestern brand of humor became more politically biting and sexually frank but never demeaning or offensive. His well-known characters, like Carnac, Aunt Blabby, and Art Fern, so familiar to multiple generations of American families, remained brash, silly, and, somehow, consistently funny.

On May 22, 1992, at the age of 66, Johnny Carson left The Tonight Show—a remarkable 30-year run in more than a half century of comedy performance that raised him to the level of national court jester and national treasure. Expected to maintain a comparable level of visibility in retirement, Carson has surprised his public by turning down nearly all requests for television appearances and interviews. Exceptions to this include cameos on Bob Hope’s 90th birthday special in 1993 and on the Late Show with David Letterman in 1994. Substituting tennis, boating, and travel for the national limelight, Carson has led a somewhat reclusive life but generated major publicity on the occasion of his successful quadruple-bypass heart surgery on March 19, 1999. He has also been noted for his generous contributions, totaling millions of dollars, for charitable causes in the United States and Africa.
