ALEX DEW, 11 - Lives Chipping Norton in Oxfordshire.
Describe yourself in three words: I am sporty, adventurous and lively.
Favourite TV show: Derren Brown's Trick of the Mind on Channel 4.
Worst TV show: The Stables (a children's show that follows a group of young riders at a riding school in Newcastle).
Favourite radio show: Chris Moyles (Radio 1 breakfast show).
... magazine: Bike.
... website: miniclip.com (free-to-play games website).
Best TV ad you've seen recently: The ad for the new Honda diesel - the "hate something, change something" one.
... and the worst: Cilit Bang. It's rubbish. I just can't stand the person presenting it.
Last ad to make you want the product: Pizza Hut!
Best ad you've ever seen: John Smith's "'Ave it!". It's become a catchphrase in the playground at school ... the one who mucks up will yell "'Ave it!"
Which brand best relates to the way you feel about life? Diesel. 'Cos it's fashionable, they only make nice stuff and all the people in the ads look really cool.
Which brand tries - but fails - to talk to your age group: Reebok. It wants to be like Nike - but isn't.
Do you like advertising in general? Yes, because it tells you about the latest and best stuff. It also lets you know the price, which is helpful to see if something's worth going out to buy.
Who is your role model and would you stop believing in them if they appeared in an ad? Alan Shearer (right). I would lose respect for him if he was ever in an ad.
KEVIN WING, 29 - Lives Kilburn, North London.
Occupation: Technical operations manager.
Describe yourself in three words: Optimistic, pensive, hungover.
Favourite TV show: The Sopranos.
Worst TV show: Desperate Housewives - overhyped American drivel. Or any reality TV show.
Favourite radio show: Fighting Talk - but only if Buncey's on it. It was better with Johnny Vaughan.
... magazine: Not my thing.
... website: Sporting Bet. But only if I'm winning.
Best TV commercial you've seen recently: Heineken - crazy Ray Liotta comedy value.
... and the worst: HSBC "the world's local bank" - a "local" money-grabbing multinational?
Last ad to make you want the product: Sam Adams (beer ad I saw in the US). Cheesy nonsense interviewing the guys working in the brewery (yeah, right). But I went right out and guzzled a cold one.
Best ad you've ever seen: Either John West salmon "bear", or the Lurpak one with the guy on the trombone. Both are stupid, silly and very funny.
Which brand best relates to the way you feel about life: Huh? Yeah, right.
Which brand tries - but fails - to talk to your age group? WKD. Guys and alcopops? Or maybe I'm missing the point.
Do you like advertising in general? No. There seems to be so much ruthless marketing these days and an oppressive obsession with how people look.
Who is your role model, and would you stop believing in them if they appeared in an ad? Steve Buscemi and no (think he has already).
MADDY WELLS, 16 - Lives Esher, Surrey.
Describe yourself in three words: Not too sure. Er, I guess I'm intelligent, funny and unique.
Favourite TV show: There are so many. ER, The OC, Desperate Housewives, Nip/Tuck and America's Next Top Model.
Worst TV show: Life As We Know It. It's boring and isn't relevant to teenage life. Compared with The OC, the acting is unconvincing - which seems odd as the actors are actually teenagers, unlike the 26-year-olds on The OC.
Favourite radio show: Music in general.
... magazine: Heat and Vogue.
... website: Hotmail, really; I use it the most, anyway.
Best TV ad you've seen recently? John Lewis' "spring stock". It's really sweet and I find the link between natural objects and man-made extras, such as "new blinds" and light in a forest, really interesting.
... and the worst: The KFC one when they sing with their mouths full. The ad is promoting bad manners in an already degenerate society. (I now sound like a really old person!) The ad makes me want to say "stop talking with your mouth full" and I find myself ignoring its message.
Last ad to make you want the product: M&S ad with the chocolate pudding at the end - yummy!
Best ad you've ever seen: The Chanel one with Nicole Kidman (right). It's beautifully produced. I also really like the Lacoste ad because the song is great to sing along to. The "Make Poverty History" ad too, because it gets its message across effectively.
Which brand best relates to the way you feel about life? Benefit make-up, because it's really quirky and fun. I also love the make-up itself!
Which brand tries - but fails - to talk to your age group? Clearasil. The ads have people with perfect skin complaining about their "spots". Sooo annoying!
Do you like advertising in general? I find most ads really dull. They're usually about loans or accident claims that aren't relevant to me. They seem to be for either much younger or older people. I turn over to music channels during ads on TV and ignore them in mags.
Who is your role model, and would you stop believing in them if they appeared in an ad? I think Adam Brody (aka Seth Cohen in The OC) is a great actor and role model. He's not classically attractive and has tried to encourage young people to vote. If he were in an ad, my reaction would depend on what it was for. If it was for a charity, fine, but if he were in a Coke ad I would lower my opinion of him.
CATHERINE FORWARD, 30 - Lives Lossiemouth, on the Moray coast in the north of Scotland.
Occupation: Full-time mum.
Describe yourself in three words: Tired, busy, happy - the order varies from day to day!
Favourite TV show: I always tape ER and Desperate Housewives. I don't often stay up for them as I'm always trying to catch up on sleep.
Worst TV show: Bo' Selector - I have to turn it off/over as quickly as possible.
Favourite radio show: I used to listen to Radio 1 in the car, but my two-year-old has other ideas and wants her music.
... magazine: That would be Good Food or Delicious.
Best TV commercial you've seen recently: I like the Scottish Health Promotion ads, as they are really effective. They promote healthy living. There is a good one aimed at putting teenagers off binge-drinking.
... and the worst: The worst is the Cilit Bang ad: I thought it was a spoof. The esure series with Michael Winner gets me reaching for the mute button on the remote control as well.
Last ad to make you want the product: Dyson. Sad, I know.
Best ad you've ever seen: The Honda "cog" ad. It's really slick and thoroughly engaging.
Which brand best relates to the way you feel about life: Very difficult question. I can't say there is one.
Which brand tries - but fails - to talk to your age group: I think the Asda ads are aimed at me as a mum who does the family shopping, although I don't believe that Sharon Osbourne shops in Asda for one moment.
Do you like advertising in general: Yes, I like intelligent, intriguing and funny ads, although they seem to be getting more bizarre - I wonder if I'm getting old!
Who is your role model, and would you stop believing in them if they appeared in an ad? My mum. I don't think she will be appearing in an ad but if she did, it would not stop me believing in her. I do think that if I see a big celebrity in an ad, I can't help but think that work must have dried up for them and they need some cash, fast. Probably not true, but it always crosses my mind.
WILLIAM DOBINSON, 69 - Lives Croydon.
Describe yourself in three words: Down-to-earth, relaxed, friendly.
Favourite TV show: Match of the Day.
Worst TV show: Any of the reality shows. They're a platform for self-obsessed people.
Favourite radio show: Capital Gold.
... magazine: Speedway Star.
... website: I don't use the internet.
Best TV commercial you've seen recently: WKD - the Karate one where the sensai asks one of his students to pull his finger. It's just comical and appeals to my sense of humour.
... and the worst: Yes Car Credit. The girl's voice drives me mad. She must say "Yes you can" about a thousand times. It's really patronising that the company seems to think we'll want their car credit after such a cheaply made ad.
Last ad to make you want the product: Guinness. I like both the drink and the ads. The white horses one was really clever and recognisable but I wouldn't say I like or buy products just because the advertising's clever.
Best ad you've ever seen: The old Hamlet ads - the mild cigar ones. They are just classic and get the point across really simply.
Which brand best relates to the way you feel about life: WKD because it appeals to my sense of humour. All the ads in the series are really funny.
Which brand tries - but fails - to talk to your age group? The ads that sell pensions or life insurance. They sound a con and I wouldn't buy anything after seeing an ad like that. I would always seek advice from an expert.
Do you like advertising in general? No. Most of the ads are a load of rubbish and I generally turn over or fast forward.
Who is your role model, and would you lose faith in them if they appeared in an ad: Jimmy Greaves. And no. I have liked Greavsie throughout his footballing career and have followed every football team he's played for. I'll always like him.
ANDREW ARMSTRONG, 54 - Lives Abington, Northants.
Occupation: Corporate financier.
Describe yourself in three words: Kind, impatient, tenacious.
Favourite TV show: Top Gear. I like the smugness of Jeremy Clarkson combined with Richard Hammond and James May darting around like two ageing pranksters. The cars are OK too.
Worst TV show: Used to be Frasier (just irritating), but I don't recall any TV show aimed at my age group currently.
Favourite radio show: Today.
... magazine: OK! or Hello!. The people in it seem to find embarrassment beyond them, but I have to pretend I am buying it for someone else.
... website: eBay. Potentially useful, but actually quite hard to find what you want at an interesting price.
Best TV commercial you've seen recently: Carlsberg.
... and the worst: Always. There are some things that simply shouldn't be advertised, before or after the watershed. And I would have thought that women might feel a little more feminine without so "in your face" an approach. A far cry from a glimpse of an ankle being sexy.
Last ad to make you want the product: Jaguar "S" type. But then I discovered passengers required surgery to sit in the back.
Best ad you've ever seen: About 15 to 20 years ago, selling Birds Eye Beefburgers ordered by a gangster's moll (what the Americans call a "steel-belted airhead"). She is being bought dinner by her Mafiosi man (sideburns and all). She has a trashy Brooklyn accent and, despite a menu full of pasta, goes for the "Boydz Oi Beeffboigerz". When the rival gang arrives she says: "Waddaya know: they godda bayand."
Which brand best relates to the way you feel about life: Issey Miyake. Unchanging, reliable, slightly understated, like a very well-made pair of grey trousers.
Which brand tries - but fails - to talk to your age group: All hair-colouring and hair-replacement products. We should learn to live with what we've got, even if it becomes less over time.
Do you like advertising in general: No, but if you watch a lot of TV, it provides the space for a pee. It's also changing radically, in both good and bad ways. I guess I watch more DVDs than TV so I sometimes try to put the programme on pause (not having Sky Plus), and feel silly.
Who is your role model, and would you stop believing in them if they appeared in an ad? My role models are (I think) good men and women who are entirely unknown. If one of them were asked, I think I'd find it immensely funny. I was asked to be in a BMW ad once, to answer one question: "Why would I buy a BMW?" My answer, "I wouldn't. I had in the past, but I did not have right-angled bum", lost me the job. Shame.
