Query: When did the first episode of Big Brother Australia air?
The series began Monday 28 April 2008 at 7:00 pm. The opening episode had the lowest-ever ratings of any launch of "Big Brother Australia". The episode mostly outrated its competitors in most timeslots—except its second half-hour when it lost out to "". The audience for the launch peaked at 1.91 million.
The series lasted a total of 84 days. The 2008 finale aired on Monday 21 July 2008 at 7:00 pm on Network Ten. It was the first "Big Brother Australia" finale to feature three finalists and the first hosted by Kyle Sandilands and Jackie O.
On 29 January 2007, Network Ten, Endemol Southern Star, and Masterfoods announced ""Australia's biggest ever integrated television promotion"", the Big Brother Starburst Golden Key, which would allow a member of the public to enter the Big Brother House as a housemate.
Unique alphanumeric codes were included in packs of Starburst, a confectionery manufactured by Masterfoods. One hundred codes gave the opportunity to audition for the BB season after it began. Of these people, one would become a housemate and be eligible to win the season and all prizes. The winner of this competition was selected during a special episode called "Golden Key". On Day 18, Nick Sady was announced the "Golden Key" winner and entered the Big Brother House.
Trevor Butler, from Broken Hill, New South Wales, entered the House on Day 0. He was the winner of Big Brother 2004 and A$1,000,000, and proposed to his girlfriend on stage. Trevor is the only "Big Brother Australia" housemate to have won $1,000,000. On 10 October 2007, Trevor made a celebrity appearance on the ABC Television series "Summer Heights High".
"The Big Bang Theory" premiered in the United States on September 24, 2007 on CBS. The series debuted in Canada on CTV in September 2007. On February 14, 2008, the series debuted in the United Kingdom on channels E4 and Channel 4. In Australia the first seven seasons of the series began airing on the Seven Network and 7mate from October 2015 and also gained the rights to season 8 in 2016, though the Nine Network has rights to air seasons nine & ten. On January 22, 2018, it was announced that Nine had acquired the rights to Season 1–8.
"Neighbours" is an Australian soap opera that first aired on the Seven Network on 18 March 1985. The first season aired at 5:30 pm in Sydney, at 6:00 pm in Melbourne and Adelaide, and at 7.00 pm in Brisbane. "Neighbours" underperformed in Sydney, where it was then moved to a 3.30 pm timeslot. By September 1985, the show was cancelled by Seven after 170 episodes. "Neighbours" was then picked up by rival network Ten, where it began screening with episode 171 on 20 January 1986 at 7:00 pm. In March 1992, the show moved to the 6:30 pm timeslot to avoid direct competition from rival soap opera "Home and Away" on the Seven Network. In 2011, Ten moved "Neighbours" to its digital secondary channel 10 Peach (formerly Eleven), due to poor ratings. The show began screening on 10 Peach on 11 January 2011, the channel's launch day. "Neighbours" currently airs at 6:30 pm each weeknight, and is the longest running drama series in Australian television.
The Australian soap opera "Neighbours" was first broadcast on the Seven Network on 18 March 1985. The show's storylines concern the domestic and professional lives of the people who live and work in the fictional suburb of Erinsborough, Melbourne. Seven decided to commission the show following the success of Watson's other soap opera, "Sons and Daughters". "Neighbours" underperformed in the Sydney market and it struggled for four months before Seven cancelled it. The show was immediately bought by rival network, Ten. Ten began screening "Neighbours" on 20 January 1986. "Neighbours" has since become the longest running series in Australian television and attained great success in the United Kingdom and launched the careers of several international stars, including Kylie Minogue and Guy Pearce.
Attempts to replicate the success of daily teen-oriented serials "Neighbours" and "Home and Away" saw the creation of "Echo Point" (1995) and "Breakers" (1999) on Network Ten. These programs foregrounded youthful attractive casts and appealing locations but the programs were not long-running successes and "Neighbours" and "Home and Away" remained the most visible and consistently successful Australian soap operas in production. In their home country, they both attracted respectable although not spectacular ratings in the early 2000s. By 2004, "Neighbours" was regularly attracting just under a million viewers per episode – considered at that time a low figure for Australian prime time television. By March 2007, the Australian audience for "Neighbours" had fallen to fewer than 700,000 a night. This prompted a revamp of the show's cast, its visual presentation, and a move away from the recently added action-oriented emphasis to refocus the show on the domestic storylines it is traditionally known for. During this period "Neighbours" and "Home and Away" continued to achieve significant ratings in the UK. This and other lucrative overseas markets, along with Australian broadcasting laws that enforce a minimum amount of domestic drama production on commercial television networks, help ensure that both programs remain in production. Both shows get higher total ratings in the UK than in Australia (the UK has three times the total population of Australia) and the UK channels make a major contribution to the production costs.
In March 1979, the government set up the Ethnic Television Review Panel, which recommended that SBS expand into television. SBS TV began test transmissions in April 1979 when it showed various foreign language programs on ABV-2 Melbourne and ABN-2 Sydney on Sunday mornings. Full-time transmission began at 6:30 pm on 24 October 1980 (United Nations Day), as Channel 0/28. The first program shown was a documentary entitled "Who Are We?", which was hosted by veteran news presenter Peter Luck. At the time, SBS was broadcasting on UHF Channel 28 and VHF Channel 0 (pronounced as "oh" and not "zero"), with a planned discontinuation of the latter at some time in the future. Bruce Gyngell, who introduced television to Australia in 1956, was given the task of introducing the first batch of programs on the new station.
The NRL Grand Final, which determines the Australian rugby league football season's premiers, is one of Australia's major sporting events and one of the largest attended club championship events in the world. Since 1999 it has been contested at Sydney's Stadium Australia, which was the primary athletics venue for the 2000 Olympic Games. The first year it was held at Stadium Australia, the National Rugby League grand final broke the record for attendance at an Australian rugby league game, with 107,999 people attending.

When the BBC revived "Doctor Who" in 2005 with Christopher Eccleston as the Doctor and with Russell T. Davies as producer, the ABC responded by scheduling the series in the prime-time 7:30pm Saturday slot.

The first and second pilots of "The Big Bang Theory" were directed by James Burrows, who did not continue with the show. The reworked second pilot led to a 13-episode order by CBS on May 14, 2007. Prior to its airing on CBS, the pilot episode was distributed on iTunes free of charge. The show premiered on September 24, 2007, and was picked up for a full 22-episode season on October 19, 2007. The show is filmed in front of a live audience, and is produced by Warner Bros. Television and Chuck Lorre Productions. Production was halted on November 6, 2007, due to the Writers Guild of America strike. Nearly three months later, on February 4, 2008, the series was temporarily replaced by a short-lived sitcom, "Welcome to The Captain". The series returned on March 17, 2008, in an earlier time slot and ultimately only 17 episodes were produced for the first season.

The Australian Grand Prix, which was one of the world's oldest Grands Prix having first run in 1928, was added to the Formula One World Championship for the first time in 1985. The race was held in Adelaide, South Australia on a street circuit on 3 November as the last race of the season. The Adelaide Street Circuit was praised by the Formula One fraternity, most of whom arrived down under fully expecting another bad street circuit like Las Vegas, Detroit and Dallas, but instead found a fast, open circuit with a 900-metre long straight where the faster cars reached over . The 50th running of the Australian Grand Prix won the Formula One Promotional Trophy for Race Promoter as the best race meeting of the year. FOCA boss and Brabham team owner Bernie Ecclestone shocked a press conference when he declared that he believed that the standard of the organisation and the circuit itself was bad news for Formula One. He then explained to the shocked media that Adelaide had raised the standards of what would be expected in the future and that several tracks in Europe already on the calendar, or hoping to be, would have to lift their own games in order to match it.

British colonisation of Australia began with the arrival of the First Fleet in Botany Bay, New South Wales, in 1788. Settlements were subsequently established in Tasmania (1803), Victoria (1803), Queensland (1824), the Northern Territory (1824), Western Australia (1826), and South Australia (1836). Australia was the exception to British imperial colonization practices, in that no treaty was drawn up setting out terms of agreement between the settlers and native proprietors, as was the case in North America, and New Zealand. Many of the men on the First Fleet had had military experience among Indian tribes in North America, and tended to attribute to the aborigines alien and misleading systems or concepts like chieftainship and tribe with which they had become acquainted in the northern hemisphere.
"EastEnders" is broadcast around the world in many English-speaking countries. New Zealand became the first to broadcast "EastEnders" overseas, the first episode being shown on 27 September 1985. This was followed by the Netherlands on 8 December 1986, Australia on 5 January 1987, Norway on 27 April, and Barcelona on 30 June (dubbed into Catalan). On 9 July 1987, it was announced that the show would be aired in the United States on PBS. BBC Worldwide licensed 200 hours of "EastEnders" for broadcast in Serbia on RTS (dubbed into Serbian); it began airing the first episode in December 1997. The series was broadcast in the United States until BBC America ceased broadcasts of the serial in 2003, amidst fan protests. In June 2004, the satellite television provider Dish Network picked up "EastEnders", broadcasting episodes starting at the point where BBC America had ceased broadcasting them, offering the series as a pay-per-view item. Episodes air two months behind the UK schedule. Episodes from prior years are still shown on various PBS stations in the US. Since 7 March 2017, "EastEnders" has been available in the United States on demand, 24 hours after it has aired in the United Kingdom via BritBox, a joint venture between BBC and ITV.
In Canada, where the episode was also broadcast on February 6, 2011, it attained 2.16 million viewers and was the ninth most-watched show of the week. Viewership declined from the previous episode, which was watched by 2.37 million viewers and ranked fifth for the week. 
The episode's Australian broadcast, on February 14, 2011, drew 1.13 million viewers, making "Glee" the fourth most-watched program of the night and the most-watched in the 18–49 demographic. It placed tenth in the weekly viewership rankings. Here, viewership registered an increase of approximately 47% over the previous episode, "A Very Glee Christmas", which aired on December 7, 2010, attracted 769,000 viewers, and failed to reach the top fifty for the week. In the UK, the episode was watched by 2.64 million viewers (2.21 million on E4, and 433,000 on E4+1), becoming the most-watched show on cable for the week.
While Carlton’s unexpected feat of reaching the grand final in 1999 has undoubtedly gone into Australian Football folklore, the finals system at the time was widely criticised for allowing a team that had finished as low as 6th to reach the grand final after losing its first finals match (a similar instance also occurred the year prior, with the 5th placed Adelaide Crows advancing on to ultimately win the 1998 premiership despite losing in the first week of the finals). Carlton were beaten by the Brisbane Lions in the qualifying final, yet still progressed to the second week of the finals to play the West Coast Eagles. This match, which was won by Carlton, also created a lot of controversy as the Eagles, who subsequently finished a place higher than Carlton and won its first finals match, had earned the right to host the final in Perth, yet were forced to play the match at the MCG due to a contractual agreement with the AFL that required at least one match to be played at that venue every week of the finals.
The theme music was adapted from the original theme used in the original "Big Brother", which aired in the Netherlands. The theme for "Big Brother Australia" was written by Siew Ooi and 001 Productions in Melbourne. The track is an extended version of the main title theme used in the first two seasons of "Big Brother" Australia, and tracks heard throughout the seasons that followed are shorter, remixed versions of this track. The original track can sometimes be heard in the background when eviction votes, or the nomination tally in the "Nominations" show, are shown on screen, or when eviction phone numbers are during a show. In 2008, the theme music was retooled into an electric amplified remix, in counterpart of the format changes that were made that year. Four years later in the 2012 revival of the program, the original theme song returned with a futuristic remix.
In the first series of "Big Brother" Australia there was no special show for nominations; they were simply shown as a part of the "Daily Show" on Tuesday evening. In the first season of the series housemates did not have to give reasons for their nominations. Subsequent seasons added a special dedicated to the nomination process. This was usually pre-taped; in "Big Brother 2005" the announcement of which housemates were nominated for eviction was presented live. For the first half of the 2008 season the housemates no longer nominated, and there was no special nominations show. When nominations resumed in the middle of that season they were shown as part of the Monday evening "Daily Show". Where there was special dedicated to the nomination process, this episode presented footage of the housemates as they explain in the "Diary Room" who they nominate for eviction.
In the United Kingdom, "Big Brother" first aired on April 12, 2012, and was watched on Sky 1 by 759,000 viewers. Viewership was down slightly from "On My Way", which attracted 763,000 viewers when it aired two weeks before. In Australia, "Big Brother" was broadcast on Thursday, April 12, 2012, a change from the Friday time slot used for the seventh through fourteenth episodes of the season. It was watched by 655,000 viewers, an increase of over 17% from the 558,000 viewers for "On My Way" on March 23, 2012. This made "Glee" the twelfth most-watched program of the night, up from fifteenth nearly three weeks before.
The series premiered on 24 May 2002, on Channel 4. The contestants were recorded 24 hours a day with cameras fixed around the house, and had to wear portable microphones. "Big Brother 3" was the first of the main series to feature a live launch. Previously, "Celebrity Big Brother 1" had featured a live launch. The launch night saw Davina give a house tour, as well as discuss rumors that had been going on about the series. She then introduced the new Housemates, and they entered the house live. Channel 4 broadcast a daily highlights show, and from the first week there was a live eviction show hosted by Davina McCall, where the evicted housemate was interviewed. In the nightly highlight episodes, viewers are shown various highlights of a specific day in the house. "Big Brother 3" saw the return of the psychiatrists providing commentary on events in the game, with the episodes featuring them being the highlights show after the most recent eviction. The live eviction episode was held on Friday, with a pre-eviction episode and an official eviction episode being held with a 60-minute gap between them. Live coverage was a major part of E4's schedule for the second year running. The season ended on 26 July 2002, lasting for a total of 64 days. "Big Brother 3" saw numerous spin-off series' occur while it was on air. The "Saturday Night Live" spin-off began this season, and saw Housemates competing in live tasks. It would last until midway through "Big Brother 5", when it was axed due to poor ratings. Though not introduced this season, the "Big Brother's Little Brother" spin-off continued throughout this season, giving the show its second season. Following this season, the special "What the Housemates Did Next" aired, and would later air after every season until "Big Brother 9".
