QI is a British comedy panel game television quiz show created and co-produced by John Lloyd, hosted by Stephen Fry, and featuring permanent panellist Alan Davies. Most of the questions are extremely obscure, making it unlikely that the correct answer will be given. To compensate, points are awarded not only for right answers, but also for interesting ones, regardless of whether they are right or even relate to the original question. Conversely, points are deducted from a panellist who gives "answers which are not only wrong, but pathetically obvious," typically answers that are generally believed to be true but in fact are misconceptions. Points are also often deducted if an obvious joke answer is given. These answers are known as forfeits, usually indicated by a loud siren, flashing lights, and the incorrect answer being displayed on screen as a form of humiliation. In addition, bonus points are often awarded or deducted for various challenges or incorrect references to a certain thing or place, varying from show to show.
For its first five series episodes premièred on BBC Four and received their first analogue airing on BBC Two a week later, with syndicated episodes of previous series shown on UKTV G2/Dave. QI has the highest viewing figures for any show on BBC Four and Dave. From series F in 2008 the show moved to BBC One, with extended-length repeats on BBC Two. For series G, the regular show moved to a pre-watershed slot, with the extended edition still shown after the watershed. In March 2011 though, it was announced that the ninth series would see the show return to a post-watershed slot on BBC Two. The eleventh series began on 6 September 2013 and is currently being broadcast on BBC Two.
