QI is a quiz style program hosted by Stephen Fry (the QI master) and broadcast by the BBC1. As well as being IQ2 backwards QI stands for Quite Interesting. The rules of the game are simple; more marks are given for being "quite interesting" than for gettting the right answer. Obvious yet wrong answers will lose you points. Each guest has an "attention seeking device", buzzers where the usual "ding" sound has been replaced with a sound effect (for example in one episode Alan Davies' buzzer goes "Cashier number four please"). Though the teams supposedly change each week you will often see guests do more than one show. The only permanent guest is Alan Davies3, who, despite playing every week, seems to lose every week as well. Obviously the show is not meant to be taken seriously and the totalling of points does seem a bit off each week. However QI is very funny, quite interesting, and worth watching.
When this was written the first series had just finished. Guests that were on the first series included Dave Gorman4, Richard E. Grant, Jo Brand, Rich Hall, Clive Anderson, Phil Jupitus, Bill Bailey, and Howard Goodall (who wrote the theme music for QI as well as Red Dwarf and Blackadder). Apparently (though I didn't notice) all the topics of the first round this series started with the letter 'A'. This is supposedly going to change each series (so second series will be 'B', third 'C', etc).
The producer of QI is John Lloyd who actually setup his own company, QI Productions, to do research and find interesting facts. John Lloyd also co-wrote 2 episodes of the Hitchhiker's Guide to the Galaxy5 radio show and the Meaning of Liff6.
