This is from Wikipedia on the page Big Brother (UK):
On 26 August 2009, it was announced by Channel 4 that the final series of Celebrity Big Brother (Series 7) broadcast from 3–29 January 2010 and Big Brother 2010 (Series 11) which started on 9 June 2010 and will be broadcast throughout summer 2010, will be the last to be aired on Channel 4. It was thought this was due to a significant fall in viewer ratings, although Channel 4 never confirmed this. They said that Big Brother had been one of the most revolutionary programmes of the last decade but had reached its natural ending point.[12] However, following the relative success of the seventh and final series of Celebrity Big Brother, rumours have spread that Big Brother may return after a one to two year break.[citation needed] Endemol and Channel 4 have neither confirmed nor denied this, and host Davina McCall has stated "I think the rumours are true. If everyone keeps up the demand for a new series and not just forget it, the producers have stated that they will bring BB back - just with a different format. Who knows if I'll still be presenting, but even if I'm not, I'll definitely tune in!"
Also on this page, it says about a possible move to Channel 5.
I hope it's true, it was a rough day for me yesterday in the TV world, last Big Brother, no more Peggy in EastEnders..
Also, at the end when the quotes were being said, it showed the diary room and Big Brother's voice saying "Big Brother will get back to you."
