Viacom are beginning to reveal their plans for C5 and it's other UK stations - and lets just say Big Brother is not at the centre of them. Although on screen they've announced they'll be back in January for Celebrity Big Brother no deal has actually been signed for next year.

Looking to Channel 5’s future he indicated that Viacom is not necessarily convinced that it must continue to air Big Brother, the broadcaster’s main ratings and revenue winner.
“Maybe we continue with Big Brother, maybe if for some reason that didn’t work out we have the ability to put out other great programming,” he said. “What is best direction for Channel 5? You can go too far with one genre even when it’s successful. That is one thing we’ve learned.
“No show is hugely popular forever so you have to keep your fingers in different pots. Big Brother has been a big performer we will leave it to the programming team to see where we go.”
