SheeN - Big Brother is basically a reality TV show where a number of strangers are locked up in a house for a few months. They are set tasks and are monitored by cameras and each week viewers can vote who to eliminate until there is 1 left who is the winner and wins money.
Buublegum - I think this may be the last series although there have been rumours of a best of series next year getting back the winners of past series to be housemates again.
I think they did something similar in the US, bringing bk past contestants for another big prize..
