‘Big Brother’ Season 21 Finale Betting Odds

• This is the 21st season for CBS’s reality show.
• ‘Big Brother’ is a spin-off of a Dutch TV series of the same name.
• ‘Big Brother’ Season 21 Finale airs September 25 at 8:00 PM Eastern.

Jim Ross doppelganger Cliff Hogg III was eliminated last time out on Big Brother which cuts the contestants down to the final three. The 90 minute season finale will air on September 25 at 8:00 PM Eastern.

Here’s the ratings rundown–they’re still pretty strong but appear to have plateaued. This isn’t surprising–just the new ‘reality’ of reality television. During the height of the genre’s popularity you’d often see a ‘snowball effect’ with viewership for the top shows growing throughout the season–and particularly as each season neared its denouement. During the final season of Game of Thrones there was a lot of discussion about it being the ‘last consensus show on television’. The metrics of reality TV–including the most popular franchises–vividly underscore this concept.

Here are the updated SPORTSINSIDER.COM odds to win Big Brother Season 21 along with some prop odds for the season finale:
