In September 1983
Joan Rivers was officially designated Carson's permanent guest host, a role she had been filling for more than a year. In 1986 she abruptly left for her own show,
The Late Show (1986), on the then-new Fox Network. Carson first learned of the show when he saw her press conference on TV. When Rivers called Carson after the announcement, he was so furious at Rivers for failing to tell him personally before the press conference that he refused to take the call. He banned Rivers from his show, canceling her three remaining weeks as guest host. Carson never forgave her for leaving and never spoke to her again. When Rivers sent Carson flowers and a note after his son Ricky died in an accident, Carson sent them back. Rivers later said that she didn't want to tell Carson before the press conference because she was afraid FOX would cancel the deal if word leaked out. Carson said he felt betrayed, not because Rivers dared to compete with him, but because she wasn't honest with him about her intentions and didn't ask for advice and his blessing.
