The 1973 series An American Family is often referred to as television's first reality show, though comparing it to Big Brother or the Kardashians would be like slotting Ingmar Bergman alongside the CBeebies. Its 12 episodes were boiled down from 300-odd hours of observational footage of the Loud family, of Santa Barbara, California, at work, rest and play.

Excepting the cows, Guernsey’s most famous resident was probably Oliver Reed, who lived there as a tax exile. The barmy This is Jinsy, the creation of Guernsey natives Chris Bran and Justin Chubb, probably isn’t a faithful depiction of the island’s life, but it’s got to be its most notable cultural export. If not that, then its most curious.

Language is, the sages tell us, intrinsic to being human. Or to what humans call “being human”, anyway. And yet, notwithstanding the 70-odd muscles and half a billion brain cells deployed every time we open our mouths, we hardly give the matter a second thought.

Education, education, education. Have we ever worried so much about how, and what, and why, and where our children are being taught? We’re so desperate, it seems, for some guidance on the matter that we barely raise an eyebrow about turning their trials and tribulations into fodder for reality television. Never mind the dubious ethics, we might learn something.

How could you not immediately warm to a new comedy series that has almost as its first line, “Maybe you should tuck your cock away while I make us a nice cup of tea”? And so begins Fresh Meat, set in a shared freshers' student house in Manchester (the line's speaker had just come across a chap wearing a jumper but no trousers), a sort of The Inbetweeners and Skins grown up a couple of years with a Peep Show aesthetic.

Baking and competition are two of my favourite things, thus when BBC Two unveiled The Great British Bake Off last year, it seemed my gluttonous, pugnacious prayers had been fulfilled. Amateurs had every possible skill challenged by the good-cop-bad-cop combination of master bakers Mary Berry and Paul Hollywood, leavened (or leadened) by ever-quirky presenters Mel and Sue. (I will avoid all recipe-related puns henceforth, I promise.)

Am I being paranoid, or are there spies everywhere these days? A quick squiz at the telly guide recently, and you'd have been forgiven for thinking that everyone in London is either employed in the security services or in making films about them. According to last night's re-opening of the Spooks case-file, anyway, there are plenty around the red-brick side-streets of Hammersmith. And when I say "spies", I don't mean Stella Rimmington at work on a novel; I mean guys in black gloves, and "accidents", and hell to pay.

And now for that difficult second album. Downton Abbey’s stately progress last autumn revived in television audiences a taste thought long dead: for populist drama offering a sepia-tinted vision of the English class system in which the well-to-do are dressed for dinner by bowing/curtsying feudal underlings. With social mobility back roughly where it was a century ago. it could almost have been a snapshot of modern UK plc. That did not stop it from being hungrily consumed as pure escapism, both here and in America where overnight it won four Emmys.

Question. How do you kill off a TV character whom, just a few episodes ago, you and your fellow scriptwriters went out of your way to render immortal? How… and why? Over two short seasons and one Christmas special, the writers of the BAFTA-winning Misfits (Best Drama Series 2010), marshalled by Howard Overden, have proved themselves singularly adept at coming up with plot devices that justify, narrative-wise, well, pretty much anything, and thereby leave the field wide open for their surrealist brand of comic pikey super-heroism.

Declaring that “everything in the world exists to end up on a postcard” is pretty courageous. But after watching the charming, gently funny Picture Postcard World of Nigel Walmsley you begin thinking that maybe, just maybe, everything was created to be depicted on a piece of card destined to be sent through the post. Holiday camps, motorways, hills, walls - all were created to become images printed on the postcards collected by deltiologists like Ronnie Barker and Michael Winner.
