Deborah Knight is across television screens seven days a week right now –  both morning and night – due to her current hectic schedule.

The  Today  co-host is on TV from 5:30 am weekdays  and pumps out three-and-a-half hours of high-pressure live television.

On top of that intensive workload,  Knight is also the  anchors of  Nine’s 6 pm evening news bulletin on Saturday and Sunday nights, but also  fills in for Peter Overton, the weekday host of Nine’s 6 pm news bulletin, when he is on leave.

And, Overton has been on leave this week, so Knight has had to step in.

Knight will be clocking off tonight for a well-earned break for two whole days. However, that means that this week alone, she will have done more than 22 hours of live broadcast presenting. Those are very high numbers.

Others in the industry are raising their eyebrows at Knight’s hectic work schedule, as the mum-of-two  is waking up at 3 am each day for  Today  and then back on TV at night for the 6 pm news.

“I’m exhausted just thinking about it,” one on-air personality at a rival network told  news.com.au.

“Not many people come to mind when I try to imagine someone else so willingly putting in those hours. Live TV is gruelling stuff. She’s a gun.”

Media consultant Steve Allen believes that Knight’s constant appearance on Channel Nine is part of a larger plan to aid the failing  Today  brand by luring some of the evening news bulletin  audience to the breakfast show.

“It’s a very clever strategy and it should, over the midterm, produce some ratings dividends.  Today  certainly needs it,” Allen said.

“It brings Nine back to where many think it should be, as the professional and slightly more up-market home of news. They’re positioning themselves as more trusted and more serious than that mums-and-dads show called  Sunrise.”

TV Tonight  editor David Knox agrees.

“When Deb was given the plum job of anchoring  Today  with Georgie Gardner, Nine indicated she would no longer be fronting prime time news bulletins in Sydney,” Knox said.

“But clearly, they recognise she is one of their most versatile presenters, whether holding her own in political interviews or never missing a beat when the news autocue goes down.

“Knight has survived TV’s revolving door where many others would not. Whether on Nine or Ten, viewers have always rated her, possibly more than some TV execs.”

Allen says that her hectic work schedule at the moment is due to her being “more humble” than many in the television industry.

“She doesn’t have any side to her, you know. She’s a lot more humble than many in TV and I think the public sees that. That’s why they really relate to her,” he said.

“If Nine is doing tracking research, which I imagine they are, she’s bound to be coming out as someone who viewers like.”

Nine  has  kept quiet about their new strategy, but it will be interesting to see whether or not viewers will follow Knight from the nightly news to the breakfast morning show.
