Since Prime Suspect introduced television viewers to the writing of Lynda La Plante, the concept of event television has lost a little of its lustre. Such was the remarkable heft of La Plante’s storyline about a serial killer and Helen Mirren’s performance as DI Jane Tennison that schedulers have ever since been sending out their pedigree crime dramas in great big lumpy chunks. Twenty years on, La Plante doesn’t quite kick down the door the way she used to.

Diehard Morsians have been harbouring murderous thoughts ever since it was announced. No doubt they communicate these to one another in fiendish acrostics and cryptic clues. It was one thing giving Lewis his own spin-off, quite another to bring Morse back to life in the form of a prequel. The heretical suggestion of Endeavour is that the grumpy old sleuth did not in fact spring fully formed into the world in the shape of John Thaw, with that slow world-weary lope and a withering glare lurking in those iridescent peepers.

Though the wind had wailed mournfully through the plot-holes of the second series of Downton Abbey, writer Julian Fellowes was in his element for this two-hour Yuletide spectacular. With the characters in place and a cluster of storylines tantalisingly in play, it boiled down to a grand game of tying knots, building climaxes and sawing off the loose ends. Framed as a Christmas shooting party with a grand gathering of friends, relatives and prospective in-laws, it was the Gosford Park of the Downton canon.

This was the television equivalent of the slaves in ancient Rome, who used to run alongside their imperial masters whispering in their ear, "Remember, you are mortal." Long before the tantrums, bombast and megalomania of The X Factor, there was New Faces, ITV's Birmingham-based talent show. Its theme tune was Carl Wayne's "You're a Star!" Alf Lawrie's film revisited the 1986 finalists of New Faces to find out how the last 25 years had treated them, and it proved to be an unassuming gem of observational film-making.

And we're done. As you'd expect for a grand final, everything was pumped up yet further. A guest spot by Coldplay came over like a Nazi rally styled by kindergarten teachers who once took an E, all rainbow squiggles and brain-obliterating strobes. The fact that the TV sound mix revealed Chris Martin's vocal weaknesses and the flimsiness of the songs beneath the band's bombast couldn't ruin the gloriously dumb spectacle.

Well, there we go. Another series of The X Factor about to splutter and crunch to a halt.

“They’re some of the greatest pop songs ever written,” declares Sir Elton John. He’s right. The Bee Gees – Barry, Maurice and Robin Gibb – are responsible for songs that will live forever, songs that are part of successive generation’s cultural furniture. Yet although the title was The Nation’s Favourite Bee Gees Song, the question asked on the ITV website was: “Just what is the greatest Bee Gees song ever?” Favourite and greatest aren’t the same thing. They can be, but they aren’t.

It's your worst nightmare. Two WPCs appear at your door and inform you that your husband has been killed in a road accident. It doesn't help that the one doing the talking looks like the uglier sister of Macbeth's witches. Then they twist the knife by telling you that there was an unknown woman in the passenger seat, now also dead. 

ITV has been cunningly trailing its Christmas bumper edition of Downton Abbey, which will feature guest stars Nigel Havers and Samantha Bond and the spectacle of Mr Bates being dragged before the beak for murdering his first wife. Now that details of the Yuletide schedules have emerged, it's clear that Downton is the one to beat on Christmas Day.

Three years after it was, as they say, "let go" by ITV, The South Bank Show, with Melvyn Bragg at the helm, is set to return on Sky Arts in 2012. The idea has been in the wind since Sky Arts revived The South Bank Show Awards in January this year, but the news was formally announced yesterday (30 November). Reflecting on a television career that began in 1963 when he landed a job as "Ken Russell's gofer", Bragg said that making arts television was what he'd always wanted to do and remains his passion.
