Australians may not have seen the last of Big Brother and his housemates.

The controversial reality TV program could find a new home at the Nine Network, which is considering a format revival after it was axed by Network Ten.

After eight years on air, the Ten network pulled the plug on Big Brother on Monday because of dwindling ratings.

Ten said the current series, which ends on July 21, would be the last.

But as devastated fans took to websites to express their disappointment and ponder what went wrong, a source from Nine revealed the network was looking at a possible revival.

The source said Nine was considering the pros and cons, but wanted a very different format.

Foxtel boss Brian Walsh said his organisation had "no interest in an ailing format like Big Brother", while Seven also said it had no desire to pick up the show.

This year's Big Brother has been plagued by poor ratings, changed rules, and criticisms of contestants and new hosts, radio shock jocks Kyle Sandilands and Jackie O.

The pair replaced original host Gretel Killeen who was dumped at the end of last year's series.

Australian production company Endemol Southern Star said it wanted to concentrate on Big Brother 08 before thinking about another series.

"We are not entering into any discussions about the Big Brother format with anyone until we have completed the current series," an Endemol spokesman told AAP.

The Big Brother concept, which began in the Netherlands in 1999, airs in dozens of countries.

It has disappeared from screens in several countries, before returning - in South Africa it was off air for three years before making a comeback.

Queensland University of Technology (QUT) television expert Jason Sternberg said he believed the series could be successfully revived if it had "less stereotyped" contestants".

This year's group included the oldest ever housemate, a bimbo, a bricklayer, a surfer, a midget and a UFO-believer.

"I think we like to see reflections of ourselves, not caricature," Dr Sternberg told AAP.

"Maybe just going back to the roots of the show where you were looking for genuinely interesting and diverse rather than deliberately controversial people might be the way to go."

Despite audience numbers being way down on previous years, Sternberg said the figures - around the one million mark on eviction nights - were not too bad.

The best ratings came from the introduction of party punk Corey Worthington, style guru Carson Kressley and former Baywatch star Pamela Anderson, who spent some of last week in the house.

Sternberg said he believed the show had failed partly because of the unpopularity of hosts Kyle and Jackie O.

Speaking on their breakfast radio show on 2DAY FM on Monday, Sandilands said he didn't care.

"I'm happy. That's six months of my life I get back," he said.

Fans lashed out at the pair.

"Kyle has really been the deciding factor, overall," one wrote on the official Big Brother website.

"He is totally useless, and has screwed everything up from beginning to end."

Many signed petitions to get the show back.

"Big Brother has been part of my life for so long now ... it's been there longer than one of my kids!," another wrote.
