The most realistic options I could see are MTV and Sky Living.

MTV is aimed at the same sort of market as Big Brother; teenagers and young adults mainly, and with the amount of reality TV they have started showing Big Brother could fit in quite well.

Sky Living, which is largely aimed at women as it shows mainly lifestyle and some reality shows (Britain & Ireland's Next Top Model for instance) could be another option. However, since Sky showed little interest in the past this seems a little more unlikely.

Watch or Really could be another option, though if it went to either of these channels it would probably become a more "family friendly" show, particularly if Watch aired it.

Overall, MTV seems like it would be the best place for Big Brother to go to.

So the next question being could MTV afford it?

I reckon they could.

No other channel will now touch the series when Channel 5 axes it. It's tainted and it's ratings have fallen even more since Channel 4 axed. The only place it could go is Channel 4. Their shows have recently being getting on average 1-2 million a week.

Maybe they could move it to Ireland and put it on an Irish channel?

The Big Brother brand is tarnished over here too, though an Irish version of Big Brother would do quite well over here I think, for a few years at least.
