New 'Over The Top' version of US Big Brother to air online

Updated: 

An online-only edition of the US version of Big Brother will begin streaming late this month.

CBS announced on Thursday that the new take on the long-running reality TV competition will be titled Big Brother: Over The Top and is set to debut September 28.

Big Brother: Over The Top will feature a new cast of house-guests competing over 10 weeks for $250,000 (£188,358) - not the show's usual $500,000 (£376,717) grand prize.

The series, which is similar to the British version aired on Channel 5 and hosted by Emma Willis, will feature live feeds and a weekly elimination.

The show is among three new projects set to debut on the CBS All Access streaming service, joining the sci-fi series Star Trek: Discovery and a spin-off of the legal drama The Good Wife.
