Rivers and Carson

Fox was looking for a host for a late-night talk show for the network's launch in October 1986. Through its purchase of Metromedia, it had been airing The Merv Griffin Show (a syndication stalwart for two decades) but opted to drop that program (leading to its cancellation) to make room for its own show. The new network offered Rivers the job at a salary higher than what NBC was paying. She accepted and Carson was blindsided by the news when he saw the press conference on television. Moments later, when Rivers called him at home, he refused to take the call.^[1]

Carson was furious when he found out about Rivers going to Fox. Carson stated that he felt betrayed by Rivers – not because she dared to compete with him, but because she was not honest with him beforehand about her intentions and did not ask him for advice and his blessing. For her part, Rivers was adamant that her problem was with NBC and not with Carson, who was like a father figure to her. She stated that she didn't want to tell Carson before the announcement was made because she was afraid Fox would cancel the deal if word leaked out. She had previously been ordered by Carson's producers and lawyers not to go to him with her problems, as they kept Carson completely insulated since he was a major source of NBC profits; thus Carson had been completely unaware of Rivers' problems with NBC.^[1]

When others obtained their own competing shows (such as David Brenner, Alan Thicke, Joey Bishop, and Pat Sajak), Carson always had them on The Tonight Show beforehand to wish them luck – and again after he had forced their show into cancellation by maintaining superior ratings. Rivers did not appear on the Tonight Show again during the remainder of Carson's tenure after 1986 or during that of his successors (in this case, Jay Leno and subsequently, Conan O'Brien) until February 17, 2014, when she appeared in a cameo on Jimmy Fallon's first show, by which point Carson had been dead for nine years.^[2] This blacklisting extended to The Late Show with David Letterman on CBS, Carson's handpicked successor. Carson continued to be friends and support Letterman and in 2004, a few weeks before Carson died, Rivers appeared on Letterman's show and made no mention of their incident, her show, or their falling out.

Rivers spoke highly of Carson the night he died on January 23, 2005, but revealed that he never spoke to her again.^[3]

Sagging ratings and carriage refusals

After a moderate start, ratings for the talk show soon sagged. The ratings struggles also made it hard for Fox to attract affiliates for its primetime launch on April 5, 1987. Some prospective affiliates, such as Milwaukee's WCGV-TV, would only sign with the network if they did not have to carry The Late Show. KPTM in Omaha refused outright out of loyalty to Carson, who hailed from Corning, Iowa, east of Omaha and started his career on local radio and television. The network acquiesced to allow some stations out of that obligation so that the network launched in primetime with as many affiliates as possible, at the cost of ratings and access to The Late Show. For instance, at the time the show launched Fox had not closed on its purchase of its Boston station, WXNE-TV (now WFXT). That station's previous owners, the Christian Broadcasting Network, objected to the show's content and refused to clear it. As a result, until Fox took control of the station in January, its audio feed aired on a low-rated AM station.

The behind-the-scenes relations between Rivers and network executives quickly eroded and Rivers was fired in May 1987. For the final show, which aired May 15, 1987, the set was vandalized with toilet paper, slime, and shaving cream. Her guests were Howie Mandel, Pee-Wee Herman, then-fledgling comedian Chris Rock, Wendy O. Williams, and show stage manager Michelle Aller as her alter-ego Mavis Vegas Davis.^[4][5] Soon afterward the program was renamed The Late Show and featured rotating guest hosts including Suzanne Somers, Richard Belzer, and Robert Townsend. After firing prospective guest host Frank Zappa, producer John Scura replaced him with Arsenio Hall, who made his debut as a talk show host. Eventually, Hall was named the permanent replacement host in mid-1987.

Arsenio Hall

Fox had originally cancelled The Late Show, but executives were stunned by the success of Hall, who was performing well among adults 18–49. In return, Hall was given a 13-week deal to host the show – however, a replacement program entitled The Wilton North Report was already in pre-production and scheduled, which meant that the deal would not be extended beyond that. Further, Hall would not be available in any event, as he was committed to filming the Eddie Murphy feature Coming to America. During the monologue of his final appearance as host, Hall stated that the reason he had agreed to only do 13 weeks was because that was as long as he was able to stay, as he had plans "to do other things."^[10]

Clint Holmes continued as announcer while Mark Hudson remained as band leader. However, the band's name changed from "Mark Hudson and the Party Boys featuring the Tramp" – as it had been known during Rivers's tenure, with "the Tramp" referring to baritone sax player Beverly Dahlke-Smith – to simply "Mark Hudson and the Late Show Band".

Guests tended to be third-string actors, with performances by lesser-known bands such as The Williams Brothers (Los Angeles) and The Amazing Pink Things (Seattle). One noteworthy guest during Hall's era was Bob Barker, then in his fifteenth year as host of the long-running game show The Price is Right.

World-famous "Earthquake Astrologer from KROQ and KFOX", Farley Malorrus, appeared as a guest following an accurate earthquake prediction in Los Angeles during October 1987.

When problems developed with Wilton North, Fox attempted to bring back Hall – but it was too late.^[11] Wilton North debuted on December 11, 1987, and was a disaster on all fronts. Fox canceled it after only 21 episodes on January 8. It started airing Late Show repeats with both Hall and Rivers on January 11, 1988, and scrambled to revive the talk show.

1988 hosts

The show came back with a new group of unknown guest hosts, including comedians Jeff Joseph and John Mulrooney; Daniel Rosen took over as announcer, while Jack Mack and the Heart Attack became the new house band. Ultimately, none of the tryout hosts would work out, and the network turned to Seattle TV personality Ross Shafer to take over The Late Show.

Ross Shafer

By the time Shafer began hosting, ratings were so low that the show could only attract newsmakers and human interest-style guests; this led to a format change in the summer to focus on tabloid and ripped-from-the-headlines stories.

Fox canceled the show effective October 28, 1988, getting out of late night until 1993, when it launched the ill-fated The Chevy Chase Show.
