Big Brother is the flagship BB programme. It airs daily on Channel 4 (with repeats on C4 and E4), and takes two general formats:

Big Brother: A daily round up of highlights from the past 24 hours in the house. On occasion, these shows are broadcast as live specials containing a twist, such as a midweek eviction or the arrival of a new housemates. These specials also feature the daily round-up.

Big Brother Live Eviction: Every Friday, one housemate is evicted from the Big Brother house in two live shows. The first contains the daily round up and the eviction announcement, whilst in the second the evictee leaves the house and recieves their first interview. This is sometimes extended if an added twist takes place.

Live shows/segments are presented by Davina McCall. Highlights are narrated by Marcus Bentley.

Big Brother's Little Brother, often shortened to Little Brother or BBLB, is a magazine-style spin-off show which airs during weekdays on E4, and on Sundays during T4 on Channel 4.

BBLB looks at Big Brother activities outside of the house. Iinterviews with celebrities, critics, journalists, ex-housemates, friends and family of current housemates, recently evicted housemates and psychologists are arguably the main feature of the show.

Other features include news bulletins, competitions, nomination announcements, and interviews with eviction host Davina McCall.

It is hosted by George Lamb and Zezi Ifore, who took over from previous host Dermot O'Leary after he left in January this year.

Big Brother's Big Mouth, often shortened to Big Mouth or BBBM, is a discussion show which airs on E4 between Tuesday and Friday, straight after the main show on Channel 4.

BBBM features a panel and an audience discussing recent events in the Big Brother house. The panel is usually made up of 2 celebrities, journalists or ex-housemates, but has contained more on occasion. On Fridays, the week's evictee has a guest role in the second half of the programme. Viewers are invited to join in with debates by phone, text or email.

The show is currently hosted by guest presenters, which change on a weekly basis. It was previously presented by Russell Brand.

During BB5 and CBB3, Big Mouth was named Big Brother's Efourum.

Big Brother Live is live streaming from the house, which is broadcast overnight on Channel 4 and E4, and for short periods during the day on E4. The feed, however, is not actually live - it is broadcast on a 15-minute time delay to enable censoring of inappropriate content, such as swearing, nudity and potentially libellous conversations. As such, it is often referred to as an 'as-live' feed.

Viewers on Sky Digital or Virgin Media can press the red button on E4 for a 24-hour stream.

Big Brother: Diary Room Uncut is broadcast on E4 on days when Big Mouth doesn't air. It is of a similar format to Big Brother highlights shows, except (as the name suggets) it focuses on conversations in the Diary Room, and footage relating to such discussions.

It is narrated by Marcus Bentley.

Big Brother's Big Ears, often shortened to Big Ears, is a twice-weekly 60-minute long online radio show, which is broadcast via the Official Big Brother Website. After broadcast, episodes are made available to download from both the website, and on the iTunes Music Store.

Interviews with guests and evictees and 'insider gossip' are features of the show. Listeners are invited to share their opinions via phone, text and other mediums.

It is hosted by Iain Lee and Gemma Cairney.
