“A bunch of beardies rooting around with trowels. On the lookout for shinbones and such. It’ll be knockout.” There will have been naysayers at the meeting when they first pitched the idea for a series about archaeology and yet nearly 20 years on Time Team is still with us. It seems the viewing public’s appetite for digging is not restricted to Titchmarsh. Mirabile dictu, as the Romans no doubt said when they dug up three wooden crosses under a temple of Venus in Jerusalem, thus inventing archaeology.

What a line-up for a sitcom; three of our most accomplished actors - Ian McKellen, Derek Jacobi and Frances de la Tour – star, and the writers are the super-talented playwright Mark Ravenhill and Gary Janetti, who used to work on Will & Grace, one of the classiest comedies on American television in decades. And what do you get? Well, not quite the laugh fest that it might have been (or may yet become), but an opener that had a reasonable hit rate.

"For youth, for change and always for the people" was the slogan with which Rupert Murdoch relaunched The Sun in 1969, having bought it from its previous owners IPC for a mere £800,000. Murdoch, the Aussie iconoclast who kept a bust of Lenin in his rooms at Oxford university in the early Fifties and claimed to be an ardent socialist, decreed that his new tabloid would be free from party political affiliations and would refuse to kow-tow to the British establishment, which he instinctively loathed.

The first minutes of Paula Milne's new three-parter are absolutely hilarious. MP Aiden Hoynes (David Tennant) resigns from his post as Business Secretary and launches an attack on the Prime Minister from the backbenches in an attempt to trigger a leadership contest, only to find his comments greeted by embarrassed silence. In a split second he has turned from a Westminster high-flier into a social leper who can clear out the House of Commons Gents like a foul gaseous emission.

You wait years for a female comedy duo to take up where French & Saunders left off, then two come along within a calendar year. Which just about counts as at once. Anna & Katy, who recently had a run on Channel 4, rely for most of their wit on a wide range of silly voices. Watson & Oliver, who have returned for a second series, feel like more traditional sketch artists. They observe and they spoof and even hint at pathos.

What if John Lennon had left The Beatles in 1962? What if they had continued without him? And what if he had still become the acid-tongued, ready-with-a-quip character the real world became familiar with? Snodgrass took those what-ifs and ran with them to depict a parallel world that was less the “hilarious comedy drama” trailed by Sky and more a gloomy, slightly creepy oddity made even more so by Ian Hart’s deft, second-nature portrayal of a Lennon floundering on life’s scrapheap.

Oh dear. Oh deary dear. Oh deary deary dear. To think that Ben Elton, who has a “written and created by” credit for this pile of poo, once helped to scale the heights of British comedy as co-writer of The Young Ones and Blackadder. Five minutes into this I was thinking, “How on earth did it get commissioned?” Oh I know, because Ben Elton, who once helped create...

And the killer is... No, that would be telling, and you might not have watched it on catch-up yet. But was the revelation worth the wait?

It feels a little as if BBC journalists are getting themselves into trouble every other week at the moment. As news emerges that new BBC chief Tony Hall will appear before MPs to discuss why they allowed a Panorama journalist to use a university field trip as cover for an exposé on North Korea, it's little wonder that the broadcaster's flagship investigative journalism programme has stuck with a far easier target this week.

“The best times I've ever had were in prison,” says Crystal, aged 23, one of the three inmates being followed in The Prisoners (this was originally planned as episode one, but was bounced from the schedules by the death of Baroness Thatcher). On the brink of being released after serving a 12-week stint for drink-related crimes, she's waxing nostalgic, while her girlfriend Toni – also due out very soon – is in tears. “I'm dreadin' getting out,” she quavers.
