 For its third series in May 2005, after covering Celebrity Big  Brother in the January of that year, "Big Brothers Efourum" became  "Big Brothers Big Mouth". The format remained almost identical with  the only major change being a set update, namely the removal of the  desk which guest panelists sat behind in favor of raised seating  platforms. New features included "Textual Preference" where the  public were polled on various trivial topics associated with the  housemates and "Big Brothers Mouthpiece" which was a 24 hour  telephone answering service people used to vent their spleen on the  daily dramas in the house.
