The show only faltered when in 1974, Seven decided to move the show from its 7:00 pm timeslot to the later 8:30 pm timeslot in an effort to attract viewers away from the then popular series Number 96 screening on the 0-10 Networks. Number 96 won the ratings battle and The $25,000 Great Temptation aired its last show in 1975. Barber then hosted the Australian version of Family Feud on the Nine Network from 1977 until 1979. In 1980, the Grundy Organization, on the advice of its founder and producer, Reg Grundy, decided to revive the $25,000 Great Temptation format using the original international title, Sale of the Century. Screened nationally on the Nine Network, Barber hosted the show from 1980–91. His hostesses during his time were Victoria Nicolls (1980–82), Delvene Delaney (1982–85) and Alyce Platt (1986–91). Barber left the show in 1991 after being offered a 12-month contract renewal instead of the usual three-year deal; Platt left at the same time. Host Glenn Ridge and co-host Jo Bailey replaced them. In 1993, Barber went on to host the short-lived Australian version of Jeopardy! (Network Ten). It has been said that its failure was partly due to placing it in the 6:00 pm timeslot against high-rating news bulletins of the day. Barber later stated in an interview that Jeopardy! Was his favorite of all the game shows he hosted in his career. After Jeopardy, Barber succeeded John Burgess as host of Wheel of Fortune (Seven Network) in July 1996 following the show's relocation from Adelaide to Sydney as part of an attempted revamp. As part of an attempt to win viewers back, the theme music that had been introduced the previous year was reinstated, the new set underwent minor changes and the former prize shop was reincarnated to an extent - contestants upon solving a puzzle were offered three prizes and one had to be selected. By the end of 1996, these changes together with the loss of the familiar Burgess resulted in poor viewing figures, and Barber decided to leave the show. Barber appeared at the beginning of the 1997 series premiere to hand the show over to Rob Elliott. During his time on TV, Barber estimates that he has hosted over 8,500 individual episodes of successful Grundy games. Recently he hosted a small competition on the Australian Cable TV network Foxtel seven nights a week called TV1's Cash
