Australia is a good market for this type of show, but I hope they don't bring back the odd showcase format there. Hopefully they can do two showcases like here. I think that odd format is part of why the show failed, but that's just my opinion.

No, the main reason why the 2003-2005 version failed, was because it was up against Deal or No Deal, which at it's time, was frequently getting over 1 million (in Australia for that timeslot. is pretty good). Ratings wise, Deal or No Deal beat out TPIR, Family Feud, Million Dollar Wheel of Fortune, and now is facing a tough competition from Millionaire Hot Seat, which has been around since about late 2008, and is currently giving Deal a real run for its money.
Also, there were rumours going around towards the end of TPIR Australia, that Larry was going to retire from television and do something else (I don't know why, as he was only 41-42 at the end of TPIR), but Channel 7 poached him literally 24 hours after he taped the last TPIR, and got him on to host Wheel of Fortune, which ironically only lasted 6 months after that.
Anyway, I can't wait to see Larry host TPIR again. In my opinion, he is 10 times better than both Barker or Carey!
