Became host of the Tonight Show in 1957 and quickly grew very popular with viewers. So popular, in fact, that the show was renamed "The Jack Paar Show" after only one year of hosting. Paar's trademark was his great ability to engage in conversation with guests that went above and beyond the generic "chat" that other hosts never rose above. He was very emotional and was known to weep on camera at times. Once he walked off the show in a huff when the network censored a joke he made referring to a "water closet". On his program he developed a regular roster of favorite guests including Zsa Zsa Gabor, Cliff Arquette, Genevieve, Hans Conried, Hermione Gingold, and Dody Goodman. After five years of hosting, he tired of the routine and switched to a weekly NBC variety series in 1962 that flopped. He next purchased a television station in Poland Springs, Maine, and sold it several years later. In 1973 he signed with ABC to compete with his NBC successor, Johnny Carson, on a limited schedule of one week a month, but failed to garner the acclaim he once enjoyed.
