The Bubble is yet another new topical panel show designed to capture the Have I Got News for You/QI audience. Its twist is to sequester participants away for three days without access to any media, and then show them a series of news and gossip stories. They must decide which are real and which are made-up. David Mitchell presents. Frank Skinner, Victoria Coren and comic Reginald D. Hunter are The Bubble's first victims.

This new comedy quiz show is based on the premise that some news stories are so preposterous that they might as well have been made up. A group of comedians and celebrities are locked away for four days in a media-free "bubble", without access to phones, TV, newspapers or the internet. Oddly enough, there was no shortage of volunteers. When they emerge, the host David Mitchell confronts them with reports, headlines and images, some real and some invented. They have to distinguish one from the other. Frank Skinner and Victoria Coren are the contestants tonight, while future guests include Marcus Brigstocke, Clive Anderson, Sue Perkins and Germaine Greer. Already a big success in Israel and Poland, the quiz looks likely be a lot of fun.

There was once a bloke in a bubble...

. . . who wasn't allowed any contact with the outside world. So he ended up telling stories like this.

David Mitchell hosts a new comedy-news quiz. Now that's what we call a game-changer. No previews available, as it's going to be topical news from the week, but it sounds like Celebrity Big Brother meets Call My Bluff and Mr & Mrs: three slebs are locked in a "media-free zone" for three days and, on exiting, have to pick out the genuine news stories from the invented ones. Tonight, it's the turn of Frank Skinner, Reginald D. Hunter and some poker player to sort out the headlines from the head-lies.

This is an odd one, a current affairs panel show that sounds like a weird hybrid of Have I Got News for You, Would I Lie to You? and Big Brother. Each week, three celebrity contestants will be locked away in a "media-free zone" without access to phones, television and the internet. After four days they will emerge, blinking into the light, to take their places in a television studio where The Bubble's quizmaster, the frighteningly learned and erudite David Mitchell, will question them on the week's news. But not just any news. The Bubble aims to dig out bizarre news and magazine stories so improbable they sound made up, and put them alongside fake items. It's down to the contestants to guess which ones are true. The Bubble's first participants are Frank Skinner, Reginald D. Hunter and Victoria Coren. We are told the format has done well overseas - but will The Bubble burst over here?

A new topical news format sees celeb panelists locked away in a media-free zone for three days. So far so good. Anything that gets Frank Skinner off the streets, even briefly, gets my vote.

But then, worse luck, they're let out to answer questions from quiz-master David Mitchell. Can they spot real news stories from fakes and should we care?

Other guests this week include the very funny ­Reginald D Hunter and Victoria Coren. Fingers crossed that Katie Price and Peter Andre can both be enticed to enter this media-free bubble and that a junior researcher "accidentally" loses the key.

Do we need another comedy news quiz? Clearly, yes... In this one, three celebs are supposedly locked in a media-free zone for three days, then on release are asked to guess which are real out of the news stories they are subsequently presented with. The ubiquitous David Mitchell hosts, so you're in safe hands.
