Producers of BBC hit series The Apprentice fear they could see their audience plummet tonight after viewers took offence at comments by their executive boss.
And with a new series of Sky's Bones airing at the same time, the hit could be huge.
In a letter to the Sunday Times self-styled "Grandad" Mike Grant, of Fife, described as "patronising" executive producer Michele Kurland's insistence that the tasks in the show should be such that: "12-year-olds watching at home with grandad can understand."
Mr Grant was not alone in finding much of the BBC's output "formulaic, unimaginative, childish."
George Flatscreen, aged 70, founder of Don't Treat Us Older Viewers Like Twats, Auntie, said: "Mr Grant's hit the nail right on the head.
"Daytime broadcasting is already patronising because they think we're all gaga. You'd think things would be better in the evenings.
"Well, the idea that we wouldn't be able to follow The Apprentice is bollocks. Utter bollocks.
"Well, Michele Kurland, my organisation has literally hundreds of members and do you know what we're going to do at 9pm today? We're all going to switch over to Sky and watch the new series of Bones!"
