Long-running reality staple "Big Brother" is so popular that the three episodes a week that usually air during its season aren't enough to satiate the show's devoted fans. They want more, which is where this late-night show fits into the equation. The program features a curated live feed from inside the house to give viewers a peek into the housemates' lives that they don't always get to see during the prime-time shows. Just don't expect anything too out-there; that is reserved for the subscription-based online feed.
Big Brother After Dark is a highly successful series.
