''The Tonight Show'' is an American late-night TalkShow on Creator/{{NBC}} that is part talk show and part VarietyShow. Creator/SteveAllen was the first host, starting in 1954; Creator/ErnieKovacs had Monday and Tuesday nights for the final (1956-1957) season due to Allen's [[Series/TheSteveAllenShow Sunday-night show]] on the same network.

In January 1957, both Allen and Kovacs were ousted and the show became ''Tonight! America After Dark'', a serious news program with Jack Lescoulie; he was booted out in June to ''Today'' and replaced for the last month by Al "Jazzbo" Collins. Allen went on to host his own talk shows until 1971.

In July 1957, Jack Paar became the full-time ''Tonight Show'' host, but he walked off in February 1960 after NBC censors took offense at one of his jokes. Paar returned to the show within a month. From April-September 1962, ''The Tonight Show'' had a series of part-time hosts, including Groucho Marx, and an orchestra led by Skitch Henderson. ''The Jack Paar Program'' premiered around that time and lasted three years.

Johnny Carson made a career of ''The Tonight Show'', acting as host from 1962-1992. During that time, Carson created many memorable characters, including Art Fern, Floyd R. Turbo, and Carnac the Magnificent, while bringing fame to his announcer Ed [=McMahon=] and his bandleader Skitch Henderson. Henderson was later replaced by Carl "Doc" Severinsen.

After Carson left the series, Jay Leno took over as host. Thus began the "talk show wars" of 1993; it had been expected that Creator/DavidLetterman, who hosted the lead-out show ''Series/LateNight with...'' since the early 1980s, would get the gig. When that didn't happen, Creator/{{CBS}} hired him as a direct competitor, ''The Late Show with David Letterman'', launched in 1993. While Letterman initially was the stronger ratings draw, Leno eventually overtook him. ''The Tonight Show'' and ''The Late Show'' remain fierce competitors. (The controversy would be dramatized in the 1996 movie ''The Late Shift''.)

Leno's format wouldn't settle for a few months, until Kevin Eubanks signed on as bandleader. Jay Leno's most enduring skits are "Headlines", a bit [[FollowTheLeader previously used by Letterman]] (under the moniker "Small Town News") on the original ''Late Night'' in the 1980s; "Jaywalking", a [[VoxPops man-on-the-street]] skit with real people that highlights American stupidity (on [[UsefulNotes/LosAngeles Hollywood Boulevard]]; talk about playing with loaded dice). He also did film clips with {{Special Effects Failure}}s with great frequency. He played a few characters, most notably Iron Jay (a dumb weightlifter), Mr. Brain (a condescending smart-aleck), and Beyondo (a "ghost" whose punchline-"first" schtick was almost identical to Carson's Carnac).

In 2004, Leno signed a contract to continue the show until 2009 and [=Conan O'Brien=] signed up to replace him when he left...but when the time grew near, Leno's ratings were still strong. NBC decided it didn't want to risk him going to another network like Letterman, so they [[KickedUpstairs kicked Leno upstairs]] to make room for Creator/ConanOBrien, who had hosted ''Series/LateNight'' since 1993. They gave Leno a similar show (''The Jay Leno Show'') at [[UsefulNotes/PrimeTime 10:00 PM]] five nights a week starting that Fall, the "five nights a week" part being a first-ever for American network prime time. For the first time, there was no "interregnum" with a failed retool (as in 1957), temporary hosts (as in 1962) or reruns (as in 1992): Leno's last show was May 29, 2009 (a Friday) and O'Brien's first was the following Monday, June 1.

However, both Conan and Leno performed well beneath the norm for their timeslots. The network itself didn't care, but affiliates lost a major chunk of ad revenue and some hinted that they weren't going to endure it for much longer -- and thus, the "talk show wars" entered its second round.

NBC attempted to fix this by moving Leno's show to ''The Tonight Show''[='s=] time slot and bumping O'Brien's critically-acclaimed but ratings-poor run back a half-hour to 12:05 AM. This wasn't received well. Leno was upset about it, as he had agreed to the arrangement by insisting the network promise both his and O'Brien's shows a full year before making any further decisions; the network agreed, [[ScrewedByTheNetwork but within less than four months they reneged]]. [[http://mediadecoder.blogs.nytimes.com/2010/01/12/conan-obrien-says-he-wont-do-tonight-show-following-leno/ O'Brien threatened to quit]], Leno had as well, and both routinely savaged NBC in their nightly opening monologues.

On January 15, 2010 Conan, tired of the whole fiasco, [[http://network.nationalpost.com/np/blogs/theampersand/archive/2010/01/15/nbc-agrees-to-pay-conan-30-million-to-leave-reports.aspx settled on a $30M payout from NBC]] (later upped to $45M to accommodate his staff) to leave ''The Tonight Show''. O'Brien came out of the debacle with most of the public, comedians, and TV writers on his side, Leno returned to ''Tonight'' and continued to host until February 2014, where he was replaced with Jimmy Fallon of ''Series/SaturdayNightLive'' fame.

And in all this history, there was the regular who didn't expect to be one — Lillian Miller (aka "Miss Miller") was an audience member on so many episodes of the Allen/Kovacs, Parr, and Carson versions that she was forced to join AFTRA. She also frequented {{Game Show}}s (including ''MatchGame'' and ''Series/WhatsMyLine''), ''The Creator/MervGriffin Show'', ''Series/TheCarolBurnettShow'', and even appeared on ''The Jack Paar Program'' in November 1962 as a guest alongside Liberace and [[UsefulNotes/MuhammadAli Cassius Clay]].

!!The other incarnations of the show provide examples of:
[[foldercontrol]]

[[folder:Steve Allen (1954-1957)]]
* ImpossiblyCoolClothes: In one episode Allen sat in a giant teacup in warm water with 200 lemon wedges while wearing a Suit of Teabags. Years later, this stunt would inspire Creator/DavidLetterman to wear Suits of Alka-Seltzer, Rice Krispies, and Velcro at various times during ''Late Night''.
[[/folder]]

[[folder:''Tonight! America After Dark'' (1957)]]
* {{Retool}}: It was more of a news show than an entertainment program.
[[/folder]]

[[folder:Jack Paar (1957-1962)]]
* TenMinuteRetirement: Paar infamouly walked off in February 1960 after NBC censors took offense at one of his jokes, but Paar returned to the show within a month. During his return episode he stated that he had a reason, namely...
-->'''Parr:''' I believe my last words before leaving were 'There's got to be a better way out there to make a living'... well, I looked... ''[audience laughter]'' and there wasn't...
* NotMakingThisUpDisclaimer: When starting a joke about a bizarre news item, Jack would often employ the phrase "I kid you not." It got to be a sort of CatchPhrase of his, to the point where Paar used it as the title of his autobiography.
* PointAndLaughShow: Paar showed clips of fans reacting to Music/TheBeatles during the very early days of Beatlemania, mainly to diss the clothing, manners, and hair length of the teenagers. Vee-Jay Records, probably believing that [[NoSuchThingAsBadPublicity any publicity is good publicity]], mentioned on sleeves shipped with promotional copies of the "Please Please Me"/"From Me to You" single that the group "just did" the Jack Parr Show. That sleeve is extremely rare.
* PreciousPuppies: On his last night, after saying his FinalSpeech, Paar ended the show by calling to his dog sitting in the audience area. "Come on, Lika. We're going home."
* SmokingIsCool: Back in the day where smoking was not only the norm, it was expected of celebrity guests. Paar and many (not all) of his celebrity guests regularly caused the set to be fogged over with smoke, thanks to five (or more) smoking guests on the set at any one time.
