Because Glitter is, or at least was, a celebrity. Huntley and Whiting, if it wasn't for their crimes you would never have heard of them. Its marketing and viewing figures and quite rightly so. It sounds like must see TV.
Only last night, I was watching a repeat of Monday's 'Bizzare ER' where a critically ill nosebleed victim was having about 3 feet of green, snot-soaked wadding pulled out of his nose by a doctor who could barely stay awake.
It was a choice between that and 'Underage and Pregnant' where a schoolboy commits statutory rape before abandoning his underage 'partner' while she prepares to move in to her new, furnished council house and explores the benefits system in eager anticipation of her 16th birthday.
I can't tell you how phrases like 'We started trying for a baby as soon as I was 14' make my heart swell with patriotic pride.
The trick is to buy one of those digital telly recorders if you haven't got Sky+. Spend some time a couple of times a week seeking out the nuggets of pure gold that hide among the mountain of dross that is modern TV scheduling.
That way, you can record The Sweeny on ITV4 in the morning; catch 'Babestation' while you're asleep at night and record Ultimate Force while Mrs Walt watches Eastenders. Then, when there's nothing on and you want to watch telly, you've got a library of televisual goodies to dip in to.
