It's a shame those of you outside the UK probably can't view the following link:

Jehovah's Witness get a prominent mention at the start of a popular comedy quiz show here in the UK, hosted by Stephen Fry, called QI. (For Quite Interesting)
What is excellent about it is the way Jehovah's Witnesses are matter-of-factly presented as being one outgrowth (along with Seventh Day Adventists) of the larger Adventist movement following the failure of the Second Coming to arrive in 1843/1844. This is poplular prime time television telling the general public, and any Jehovah's Witnesses watching the programme, that JWs are not unique, that they come from a lineage of apocalyptic groups predicting The End, and that they are not even the largest group to emerge from this background - the Seventh Day Adventists are mentioned as having 15 million members. One of the panelists gets it slightly wrong when he suggests JWs predicted the end of the world in 1920. If he had said 1914, 1925 or 1975 instead he would have been spot on.
