Big Brother is a reality television show where, in each series, a group of people live together in the Big Brother House, isolated from the outside world but continuously watched by television cameras. Each series lasts for around three months, and there are usually fewer than 16 participants.

The housemates try to win a cash prize by avoiding periodic evictions from the house.

There ia also A Celebrity Big Brother where celebritys are put into the big brother house for no longer then 2-3 weeks.
It Can Be Good But Usualy Dull For example:
Day 22 12:00 pm In the big brother house. After A Day Over arguing over crushed jaffa cakes, Katie Goes to bed.

Day 22 12:03 pm Jen gives evils to the cameras.

Day 22 12:05 pm Dan Picks his nose in the Dairy Room.

A full sized keg of beer.

Full kegs contain 15.5 gallons of beer, which is exactly 1984 US fluid ounces.

Thus, "Big Brother" is a reference to George Orwell's book "1984", as well as a descriptive nickname for the beer container -- similar to "Tall Boy" (a tall, narrow 24oz beer can).
Hobo 1: Wanna go get some tall boys?
Hobo 2: Yeah, but why don't we get a Big Brother instead?
Hobo 1: Cause we're broke-ass hobos.
Hobo 2: Oh yeah, huh.

A bizarre cross between The Real World and Survivor, with a dash of 1984 for flavor. Has spawned multiple variants around the world.

A bunch of people, called houseguests, enter a giant house with no contact with the outside world. There, they will be voted off one by one until a winner is decided.

Insanely popular in the United Kingdom, for whatever reason. There have been, as of now, twenty-eight seasons, thirteen of which involved celebrities. Compare this to the US, where there have been only sixteen seasons, none of which feature celebrities.
Yeah, I like Big Brother. Doesn't mean I'm British.
