QI ran for 23 seasons and 369 episodes across BBC One, BBC Four and BBC Two, and it still plays the same game today. The premise is simple: a quiz about obscure facts, where correct answers earn points, interesting answers earn bonus points, and obviously wrong answers lose them. That sounds easy. It rarely is.

The Format
Each episode brings together a panel of comedians led by Alan Davies, who serves as the permanent fixture, with three guests joining him. The host, Sandi Toksvig, asks questions that are deliberately off the beaten track. The show rewards answers that are quite interesting, not necessarily right, and punishes answers that are painfully obvious.
Points are added for correct answers and for answers that are genuinely interesting, regardless of whether they answer the question correctly. Points are taken away for answers that are wrong and obvious, the kind of answer that everyone believes is right but isn’t. Those answers are marked with a klaxon, flashing lights and a flashing screen showing the wrong answer.
The Klaxon System
The klaxon is the show’s signature punishment. When a panelist offers an answer that is wrong and obvious, the klaxon sounds, the lights flash, and the wrong answer appears on the screen behind the panelists. It is a theatrical moment, and it lands every time.
What Makes It Work
The show’s philosophy is that “everything is interesting if looked at in the right way.” That attitude carries through every episode. The questions are designed to be so obscure that the correct answer is unlikely to be given, which means the panelists are rewarded for thinking creatively rather than simply recalling information.
Many factual errors in the show have been corrected in later episodes or on the show’s blog.
The Panel
Alan Davies is the show’s constant presence, and he remains the best-known face of the series. The guest panelists are mostly comedians, and their humor often carries the lighter moments. The combination of Davies’s steady presence and the guests’ varied personalities keeps each episode fresh.
How It Began
The first five series were shown between 2003 and 2007, with episodes premiering on BBC Four before moving to other channels. The show’s creator, John Lloyd, co-produced the series, and it was presented by Stephen Fry from its beginning in 2003 until 2016.

Our View
QI is a show that rewards curiosity over knowledge. It is funny, clever and occasionally frustrating, but it is almost always engaging. The klaxon system gives the show a distinctive identity, and the philosophy that everything is interesting if looked at the right way is genuinely thought-provoking.
The show has run for decades, and it shows no signs of losing its appeal. Its format rewards interesting answers and punishes obvious ones, and that balance has held up over hundreds of episodes.
