31 January 2005 - Desperate Housewives premieres on Channel Seven. It proves to be a massive ratings hit helping the network to a strong start to the year (though Nine would ultimately win yet another ratings season).
1 February 1981: A new sitcom from the producers of Kingswood Country debuts on ATN7. Daily at Dawn is set in the office of a major metropolitan newspaper. Amongst the characters is a slovenly sports reporter (Paul Chubb), a hard nosed female reporter (Noelene Brown), her ex husband and editor of the paper (Henri Szeps) and a gay showbiz reporter (Terry Bader).
1 February 1982: Katrina Lee returns to the TEN10 Eyewitness News desk for the year with yet another newsreading partner. Tim Webster, formerly the newsreader on Good Morning Australia, follows Ron Wilson in the role. Wilson had held the job for sixteen months following the departure of John Bailey to weekend news for health reasons. Katrina and Tim would be the team that would take TEN10 to the top of the news ratings in 1984.
Notice Katrina, the longer serving newsreader and more seasoned journalist, is seated on the left. This would be a problem in years to come when Ten decides to make a concerted effort to strengthen Tim Webster’s image. The person seated on the lefthand side of the screen is usually considered to be the dominant member of the team.
1 February 2010: My Kitchen Rules debuts on Seven. It is seen as Seven’s answer to MasterChef Australia which pulled more than 3.3 million for the season 1 grand final in 2009. MKR’s judges Manu Feildel and Pete Evans had each appeared on celebrity chef challenges on season 1 of MC, with Manu winning and Pete losing. The first season of MKR wasn’t a ratings success, often coming second in the timeslot to Nine’s US comedies Two and a Half Men, and The Big Bang Theory. It was not until season 2 in 2011 that MKR started winning in the 7.30pm timeslot, and the show would continue its domination until 2017, when Nine changed the format of Married at First Sight and moved it to the 7.30pm timeslot against MKR.
So, no stereotypes then. 
And Robert Hughes
February 1, 2016 - Seven News updates its theme after 11-and-a-but years of the 2004-15 theme. A new set is introduced in Sydney and Sunrise is relaunched as well.
I vaguely remember watching Daily At Dawn at the time, but I was 9 at the time so I’m sure mum would never have approved me doing so 
I seem to recall it was very short-lived. Though I remember one gag. There was a news story about a streaker at some sporting event. The instruction was to put the picture of the streaker on the front page but censor it. They ended up running the pic on the front page, with a black bar covering the streaker’s eyes. Cast all look in shock as they see the front page.
“Oh, no this is a disaster!”, one says.
Noeline snaps back, grinning, “No, we’ll sell a million!”
I obviously found it very amusing at the age of 9 that it’s the only line from the show that I remember!
And i guess since Robert Hughes was in the cast this show will probably never be repeated.
I’m not sure it ever was, anyway.

I can remember it being repeated in the afternoons on Seven a few years after it was axed. And if I’m not mistaken, maybe in a late night, after midnight, or early morning timeslot also.
Seven used to be good at repeating their old shows in that way but they never seem to do it these days.
It had a lot of well-known actors in it but I guess the writing let it down.
3 February 1982: New American “super-soap” Dynasty screens for the first time on TCN9 with a movie length episode. The show had premiered on GTV9 on January 25. Nine hopes the saga of mega rich, bed hopping families will rival Ten’s Dallas in popularity. Australian viewers spend the next eight years wondering if it should be pronounced “Din-asty” or “Dine-asty” every time the show is mentioned on Entertainment This Week.
3 February 1987: Seven’s Eleven AM reports the death of Liberace and broadcasts a pre prepared obituary report… two days before the pianist actually passes away.
NBC’s Tom Brokaw had recorded a dummy story for broadcast in NBC Nightly News should Liberace die before that day’s edition was broadcast on the west coast. Problem was NBC failed to alert it’s affiliates the story was a “blind lead” and the information was reported as fact by Seven and quite a few stations in the US. Seven’s news boss admits to being “embarrassed” by the error.
February 3, 2014 - Today Tonight is axed on the east coast with Seven News in Sydney, Melbourne and Brisbane extending to one hour.
Also on that very same day: NBN News relaunches with a slightly tweaked set that would be used until receiving their current TCN/QTQ “hand me down” hybrid in 2017, new graphics* and new theme music.
*OK, so the weather graphics weren’t relaunched until later in 2014. But even so…with elements of NBN News’ 2014 graphics package utilising some elements of the then-current Nine News graphics package that launched just one week earlier, it was probably when the (very long) Nine-ification of NBN Television began!
Perth and Adelaide editions remained until last year
4 February 1963: ATN7 brings pre school to Sydney lounge rooms when they introduce Romper Room to Australian audiences. “Miss Susan”, fresh from the US where she received special training from the people who devised the concept, entertains children with educational and physical activities for one hour each morning from 10am. The show is initially broadcast live.
4 February 1985: ATN7 introduces a host and hostess to their breakfast programming lineup for young viewers. Alex Wileman, best known as the Mellow Yellow girl and hostess on The Love Game, joins Michael Pope to present Cartoon Connection.
4 February 1991: Struggling Ten introduces another tired old game show format to the schedule. Let’s Make A Deal with comedian Vince Sorrenti airs at 5.30pm as a lead in to the 30 minute Eyewitness News bulletin. The show, produced by Fremantle Television, is one of the first to be made at Ten’s old North Ryde studios after Hoyts Television takes over management of the site. Within weeks the show would be known as Let’s Make A Dud.

I thought QTQ9’s Romper Room was the first in Australia but this clearly pre-dates it. QTQ’s version started later in 1963. They had “Miss Patricia”
SAS10 started its own version in 1965 with “Miss Michelle” (Michele Kenny). I understand that this version was also sold to ATV0 for screening in Melbourne, but Romper Room’s history is always something I’m a bit hazy on because it seemed to have its own history in each city up until Seven took it over nationally (ignoring the version that continued on NBN3). Seven took it over nationally maybe around 1975?
Michael Pope? Did Michael Horrocks come later?
HSV didn’t get Cartoon Connection until later in 1987, part of the push by Fairfax to wipe out production from HSV and put in all the Sydney shows that HSV never picked up previously. (e.g. see also TWT, Newsworld, Sportsworld)
Did HSV7 produce it’s own Newsworld prior to 1987?
they did but it was just a straight news bulletin, and then it got replaced by the Sydney version in 1987 with Clive Robertson which was very different. Admittedly it went on to rate well for them until Graham Kennedy’s News Show came along in 1988.
