From Real.com:
Why are the cameras showing a fireplace? I thought Big Brother 7 had 24/7 feeds.
Answer
The Big Brother 7 house this year includes a gas fireplace. When the show is airing on TV (and at select other times), the cameras will be pointed at the house fireplace.
At any time during the Big Brother 7: All-Stars season, if you see the fireplace, the feed is not down. CBS has reserved the right to limit, delay, or block the live camera feeds at these times:
- When the live show airs (after the premiere on July 6th, on Tuesdays, Thursdays, and Sundays, 8pm ET/PT).
- During potentially inappropriate scenes (including nudity or other adult rated situations).
- Intermittently during houseguest challenges, preparation for the live show, and other times chosen by CBS.
Because CBS airs the program on both television and the Internet, this keeps the content new and original for all viewers of the TV show. CBS also displays this policy when you sign up for Big Brother
Looks like we get a fireplace this year instead of the fish.
