QI (short for Quite Interesting) is a BBC comedy panel game television show that began in 2003. It was created by John Lloyd, and was hosted by Stephen Fry until the end of Series 13 [M] after which Sandi Toksvig took over, and features permanent panellist Alan Davies. Each series covers topics that begin with a different letter of the alphabet; for example, the first series covered topics whose word began with "A". Thus it is referred to as "Series A" instead of "Series One".
