The X Factor (British TV series) series 10

The X Factor is a British television music competition to find new singing talent. The tenth series began airing on ITV on 31 August, and finished on 15 December 2013. Dermot O'Leary returned to present the main show on ITV and Caroline Flack was back to present spin-off show The Xtra Factor on ITV2, along with comedian Matt Richardson, who replaced Olly Murs. Flack also presented backstage segments during the live shows. Louis Walsh, Gary Barlow and Nicole Scherzinger returned as judges for their respective tenth, third and second series, with Sharon Osbourne returning to replace Tulisa after five series away. This was Barlow's final series as a judge. Osbourne and Scherzinger also departed the series, but reprised their roles as judges with Walsh again in series 13 and series 14.

Auditions for the series started in March 2013 with mobile auditions taking place in 23 towns and cities. After this, open auditions in front of producers took place in April and May in London, Birmingham, Cardiff, Manchester and Glasgow. Auditions in front of the judges occurred in June and July in the same five cities, with two types of audition: auditionees who were successful in a first audition in an audition room, used for the first time since series 5, went on to attend an audition in an arena, which replaced the rooms in series 6. After bootcamp and judges' houses, the live shows began on 12 October 2013, and ran until the final on 15 December 2013, which was won by over 25s contestant Sam Bailey. This marked the first time someone from the over 25s category had won the show since Steve Brookstein won series 1 in 2004. It also marked the first time that Osbourne had been the winning mentor, having failed during her first stint on the show. As the winner, Bailey received a £1 million recording contract with Syco Music, and also supported Beyoncé at one of her shows during the UK leg of her The Mrs. Carter Show World Tour in 2014.

This was the final series of the three-year deal signed by Simon Cowell in 2010, before it was announced by ITV on 15 November that the show's contract was extended by a further three years, keeping it on air until 2016.

Judges, Presenters and Other Personnel
It was reported on 22 February 2013 that Tulisa would not return for series 10, after being a judge for two series. She initially denied this and said she wanted to return, However, Tulisa confirmed on 21 May after months of speculation that she would be departing the show. The following day, it was confirmed that original judge Sharon Osbourne, who had been on the panel from series 1 to series 4 would join the remaining three judges from series 9, Louis Walsh, Gary Barlow and Nicole Scherzinger, ending rumours that Scherzinger may leave to focus on her second studio album and be replaced by series 9 guest judge Mel B, which happened in series 11.

Osbourne stated in July that she was back for just one series, "to go out on a high", and during the first live show, Barlow revealed that this would be his last series on the show. Walsh, who had appeared on the show since its inception, announced he would be leaving the show after this series, although he later said he "might come back" if Simon Cowell returned, and later still he said he would most likely continue, claiming "I'm having so much fun this year, I might stay". Walsh eventually confirmed his return for series 11, following the returns of both Cowell and Cheryl Cole.

Dermot O'Leary returned to present the main show on ITV for his seventh series, whilst Caroline Flack came back to present spin-off show The Xtra Factor on ITV2. Olly Murs, Flack's co-presenter for series 8 and 9, wanted to focus on his music career and therefore did not come back. On 29 May, it was announced that comedian Matt Richardson would co-present The Xtra Factor with Flack, after reports that Nick Grimshaw, Dave Berry or Rylan Clark may replace Murs. Flack also presented backstage on the main X Factor programme, during the live shows on Saturdays. Yvie Burnett returned as vocal coach. Brian Burke left as creative director and was replaced by Jerry Reeve and Mark "Swany" Hart.

Mobile auditions
Between 25 March and 1 April 2013, mobile auditions took place in Inverness, Great Yarmouth, Warrington, Aberdeen, Colchester, Hull, Dumfries, Grimsby, Romford, Belfast, Newport on the Isle of Wight, Sunderland, Wakefield, Bangor, Middlesbrough, Yeovil, Aberystwyth, Blackburn, Dublin, Blackpool, Cork, Merthyr Tydfil and Newport in Wales. It was reported that around 20 people attended Colchester auditions on 26 March and producers tried to convince passers-by to audition.

Open auditions
For the first time since series 6, auditions took place in five cities instead of six. Open auditions in front of the show's producers began in London (ExCeL London) on 6 April and continued in Birmingham (International Convention Centre) on 13 April, Cardiff (Millennium Stadium) on 20 April, and Manchester (Old Trafford) on 27 April, before concluding in Glasgow (SECC) on 1 May. Auditions were not held in Liverpool this year, after it was one of the locations in the past two series. Producers said that they were "mixing it up", although reports claim that they were unimpressed with talent in Liverpool, despite four finalists— Ray Quinn (series 3), Rebecca Ferguson (series 7), Marcus Collins (series 8) and Christopher Maloney (series 9)—coming from Liverpool. Additionally, auditions returned to Birmingham after being replaced by Newcastle in series 9. Producers previously held auditions in Newcastle instead of Birmingham because they thought that Birmingham provided "no memorable talent", but reportedly decided to return there after "disappointing" results in Newcastle. Almost 8,000 auditionees attended in London, whilst Cardiff attracted at least 3,000, Birmingham produced around 5,000, over 4,000 auditioned in Manchester and over 2,000 in Glasgow.

Judges' auditions
This series saw the return of the original auditions format last used in series 5, where auditionees performed in a room in front of the judges. Those who were successful in the room auditions then faced a second audition in an arena—the format used since series 6—to prove they can impress an audience. If they were successful in this audition, they entered the bootcamp stage of the competition. Cowell hoped the "intimate" room auditions would increase ratings. The room auditions in front of the judges began in Glasgow on 4 June at the Hilton Glasgow Grosvenor Hotel and continued in Birmingham on 10 June at the International Convention Centre. Manchester auditions took place over three days from 13 to 15 June at Old Trafford, followed by London auditions which also took place over three days, from 19 to 21 June at ExCeL London. Due to a lack of successful groups, extra auditions specifically for groups took place on 1 July at Price Studios in Battersea, London. Auditions then concluded in Cardiff on 3 July at the Motorpoint Arena. The arena auditions took place at a single venue, Wembley Arena, over four days, from 15 to 18 July. The broadcast of auditions started on 31 August 2013, with room auditions being shown on Saturday nights and arena auditions on Sundays.

The first room audition episode aired on 31 August, and featured auditions from Cardiff, Manchester, London and Birmingham. The second room audition episode featured auditions from Manchester, Cardiff and Glasgow. The third room audition episode showcased auditions from London, Manchester, Birmingham and Glasgow.

Numerous contestants from previous series returned to audition again for this series, including: Amy Mottram, who was Tulisa's wildcard contestant in series 9 and failed to be chosen ahead of Maloney as the 13th contestant; Terry Winstanley, who made it to judges' houses in series 8; Johnny Rocco, whose audition in series 4 ended with him "cursing" Walsh after getting a "no" from all four judges; John Adams, who reached bootcamp in series 8; Curtis Golden, Joseph Whelan and Gathan Cheema, all of whom got to bootcamp in series 9; Stephanie Woods, who got to judges' houses in series 4; Jade Richards, who got to judges' houses in series 8 and bootcamp in series 9; and Melanie McCabe, who got to bootcamp in series 5 and 9 and to judges' houses in series 8. Also auditioning again were groups Rough Copy, who were initially to through to judges' houses in series 9 but had to back out due to visa problems, The Dolly Rockers, who made it to judges' houses in series 3 and James Bellamy and Duane Lamonte from Brick City who both made it to judges' houses in series 2 and series 6 respectively. Another notable group to audition were 1990s pop rock band Next of Kin, who were once labelled "the British Hanson".

Bootcamp/Six Chair Challenge
On 17 April 2013, it was reported that this series' bootcamp could be changed and be conducted abroad like judges' houses, however, it was later confirmed that bootcamp would take place at Wembley Arena over four days, across three sessions between 9 and 12 August. It was reported that Cowell was planning to give advice on which acts should progress through this stage, meeting with the judges on his yacht to give opinions on the acts, but further reports claimed that due to a pregnancy scandal, Cowell would instead speak to the judges by telephone, as he did in series 9. However, this did not happen.

In a change to the usual format, the judges were allocated their categories before bootcamp, via a phonecall from executive producer Richard Holloway. Walsh has the Boys, Scherzinger had the Girls, Osbourne has the Over 25s and Barlow has the Groups. On the first day of bootcamp, soloists were put into groups of three within their category, and groups were put into pairs. They had to perform within that pair or group, and the category judge would then decide who would continue. There was then a change in the format, that saw the judges choose the acts to advance to judges' houses immediately after their bootcamp performance, instead of waiting until everyone had performed. Each judge had six places to their judges house, and they granted a 'seat' to the performers they wanted to advance in their category. However, if a judge already chose six acts for their category, they could replace them if they preferred a later performer, therefore causing bootcamp to be branded the 'ultimate game of musical chairs' or even Six Chair Challenge was introduced. Bootcamp was broadcast over two episodes, each of 90 minutes, on 28 and 29 September.

Judges' houses
Judges' houses took place in September. Each judge took the remaining members of their category to an overseas location, and had guests to assist them in their decisions. Walsh was assisted by Nicole Appleton and Shane Filan along with the returning Sinitta (who's Walsh's assists for the Second Time and Ninth Overall Appearances in the Judges' Houses) when he mentored the Boys in Saint-Tropez, France, in a property worth £10.5 million, next door to a property owned by Nicolas Sarkozy, whose gardeners interrupted filming. Osbourne took the Over 25s to her own home in Beverly Hills, California, assisted by Robbie Williams; Barlow was assisted by series 6 runner-up and former The Xtra Factor co-presenter Olly Murs to mentor the Groups in New York City; and Scherzinger took the Girls to Antigua with Mary J. Blige, staying at the St James Club resort. Groups Code 4 and Rough Copy were forced to lose a member each during judges' houses because of visa problems. At judges' houses, Each act performed two songs for their mentor and his/her guest judge, although only one song was mentioned and shown on the main show, with the other song shown on The Xtra Factor instead (although only the acts who made it to the live shows had their second songs shown). Judges' houses was broadcast over two programmes, on 5 and 6 October.

Live shows
The live shows started on 12 October. As in previous series, each week's song choices followed a particular theme. Each contestant performed on Saturday, while eliminations and guest performances took place on Sunday. For the first three weeks, a new "flash vote" took place at the end of each Saturday night show, where the voting lines opened for about eight minutes, and the act with the fewest votes faced the "sing-off" (formerly called the "final showdown") on Sunday. Voting lines for the remaining contestants then reopened, and stayed open until the Sunday shows, where the second contestant to face the "sing-off" was revealed. "Deadlock", where the act with the fewest public votes is eliminated after the judges' votes are tied, was eliminated while there was a flash vote, and instead, in the event that judges' votes were tied, the contestant that lost the flash vote was eliminated. However, in week 4 the flash vote was rested because of Nile Rodgers and Chic's performance, meaning there was not enough time at the end of the show for the flash vote, and "deadlock" would have returned if the judges' votes had been tied, and the flash vote did not return after this. Deadlock was used in weeks 8 and 9 due to tie votes from the judges.

The final took place at the normal venue, Wembley Arena on 14 and 15 December 2013.

Musical guests
Each results show featured musical performances from at least two artists, while occasionally, artists performed on the main performances show. Ellie Goulding and Cher performed on the first results show, Robin Thicke and Katy Perry performed on the second, and The Wanted and Lady Gaga performed on the third. Nile Rodgers and Chic performed a medley of three songs on the fourth live show, in what was billed as a "special edition" of The X Factor. Little Mix performed on the fourth live results show, followed by Taylor Swift with Gary Lightbody. Robbie Williams and Celine Dion appeared on the fifth results show, though Dion's performance was pre-recorded. The sixth live results show featured performances from judge Gary Barlow, who was relaunching his solo career, and Miley Cyrus. Olly Murs performed on the seventh live show, then JLS, Mary J. Blige with Jessie J, and One Direction performed on the seventh live results show. Rebecca Ferguson and James Arthur performed on the eighth results show, Leona Lewis and Michael Bublé performed on the semi-final live results show, Tom Odell and The Killers performed in the first show of the final, and One Direction, Perry, Elton John and Barlow performed in the second show of the final.

 * Scherzinger: Kingsland Road – backed her own act, Tamera Foster.
 * Barlow: Tamera Foster – backed his own act, Kingsland Road.

 * Walsh: Kingsland Road – said that Foster "sang her heart out" in her sing-off performance and had "star quality".

However, voting statistics revealed that Kingsland Road received more votes than Foster which meant that if Walsh sent the result to deadlock, Kingsland Road would have been saved.

 * Osbourne: Hannah Barrett – because it was Barrett's third time in the bottom two.
 * Walsh: Hannah Barrett – gave no reason, but on The Xtra Factor he said that it was because Barrett had been in the sing-off three times and Rough Copy had more to give.

 * Osbourne: Tamera Foster – said that Friend delivered "an organic natural performance" in the sing-off.

Prize
As the winner, Sam Bailey received a £1 million recording contract with Syco Music, she went on to join Beyoncé Knowles for one night in Birmingham, on the UK leg of her The Mrs. Carter Show World Tour in 2014. Bailey's winner's single "Skyscraper" was released on 16 December, the day after she won, and sold over 100,000 copies to become the Christmas number one on 22 December. This made Bailey the first X Factor winner since Matt Cardle in 2010 to gain the Christmas number one (series 8 winners Little Mix and series 9 winner James Arthur both released their winners' singles two weeks before the Christmas chart, thus avoiding the Christmas number-one battle, although they both charted in the top three of the Christmas chart regardless). On 24 November, it was revealed that the winner's single, like Arthur's, would be a charity release to raise money for Together for Short Lives, and also the Great Ormond Street Hospital. If Nicholas McDonald had won, he would have released "Superman (It's Not Easy)" as his winner's single.

Ratings
The series launch on 31 August 2013 received average overnight ratings of 8.78 million, a 40% share of the viewing audience at that time, and peaked at 9.08 million. The average rating was 680,000 more viewers than the series 9 launch, but still 2.5 million fewer than the series 8 launch. The first Sunday show the following night attracted average overnight ratings of 9.21 million, a 36.2% audience share. This was officially the highest rated episode of the series. The following Saturday, on 7 September, the ratings dropped to 840,000 fewer than the launch, an overnight rating of 7.94 million. The second Sunday show saw viewers fall by 300,000 viewers compared to the previous Sunday, but it was up by more than 1 million on the fourth auditions episode of series 9. The ratings for the third Saturday show were up on the second by 710,000, with an average overnight rating of 8.65 million. The next day, the average overnight ratings reached 9.08 million and peaked at 10.7 million. The final weekend of auditions saw viewers decrease by around 200,000 on the Saturday, though the next day saw the show reach a new peak audience of 9.42 million, according to overnight figures.

Trailer
The mash-up video trailer promoting the tenth series was published as a "mash up of all the best a decade of X Factor has to offer" on 25 July 2013. The trailer consists of various music videos from 13 past contestants: winners Shayne Ward, Leona Lewis, Alexandra Burke, Joe McElderry, Little Mix and James Arthur, and finalists One Direction, JLS, Olly Murs, Union J, Amelia Lily, Cher Lloyd and Misha B. However, fans questioned the absence of successful contestants Diana Vickers and Rebecca Ferguson, and winners Steve Brookstein, Leon Jackson and Matt Cardle were also not included. Cardle's manager Will Talbot said that he believed the show was "attempting to erase Matt from the history books. [...] In truth, it pretty much sums up Syco's attitude to him during the months after he inconveniently (for them) won the show. Unfortunately there is a misconception that Matt has slagged off the show and fallen out with Sony but this is not true." Cardle later described being omitted from the advert as "disappointing", especially for fans who would have liked to have seen him in it. Melanie C, who has collaborated with Cardle, was more critical, saying: "I think it's really f****** rude the way they have left him out."

Format changes
The change to the format of the auditions was criticised by Alex Fletcher from entertainment news website Digital Spy, who said he could not see the logic in having auditions broadcast on both Saturdays and Sundays, as complaints from series 9 were not about needing extra auditions, but about "dour judges" and "underwhelming finalists". He praised the return of the audition room but felt that "the producers and [Simon] Cowell evidently weren't confident in the format change and have kept the arena auditions as an extra second round," stating that the Bootcamp stage of the competition could have been used to show "how the acts cope under pressure with a live audience," adding that "the Sunday show feels like a bit of a formality" and "generally the singers who stun us on Saturday will impress again on Sunday." He said that "the extra Sunday helping of The X Factor will still rate much higher than anything else that was going to air in that slot for ITV. So for the bean counters and X Factor PR machine it will probably be labelled a hit. In the long-term, however, I fear this 'Supersized X Factor' may lead some viewers to reach for their remotes suffering from reality TV fatigue."

Additionally, Fletcher was critical of the format change to bootcamp, saying "The show can be cruel for those taking part, brutal for those who don't make the grade, and its fickleness is nothing compared to the harsh realities of the music industry. However, the argument that 'the music industry is meaner' fell apart this week. [...] I refuse to believe that anyone in the music industry has even been given a contract, told they're brilliant and then forced to watch 15 other people sing and have that contract ripped up in front of their faces. And even if they have, I bet they didn't have an audience of 4,000 people chanting at them to be on their way. This was reality TV at its most cruel." He wondered if the change was a "desperate attempt to create interest in a series that has performed solidly in the ratings, but without creating any real talking points or memorable moments", and said that "watching Karen Harding, Lydia Lucy and Sheena McHugh get put into the Top 6 and then have the dream of a spot at Judges' Houses snatched away from them felt needlessly mean. Whether the trio deserved to make Judges' Houses or not felt irrelevant. The audience finger-pointing and the chanting of 'Swap! Swap! Swap!' made the whole process terribly ugly." He questioned the show's producers' "need to make it even more vicious", opined that the new twist "definitely undermines the credibility of the show's judges", and said, "The whole twist felt contrived and unpleasant, and I hope it won't be returning in 2014."

Fans and viewers of the show also criticised the bootcamp format, with some viewers said to be fearing for the contestants' wellbeing, with one calling it "blood sport". Singer Lily Allen, who watched the show, said, "When did become alright to f*** with people's minds. X Factor has got fully mean." Contestant Lydia Lucy, who was initially chosen to be in Scherzinger's final six but was replaced by Abi Alton, said, "It still hasn't sunk in. I've been absolutely devastated. [...] If Simon Cowell was in front of me now I'd tell him to change the format back to how it was. This way is like dangling a carrot in front of someone and then taking it away."

The new "flash vote" twist during the live shows was met negatively by Lorna Simpson, who was the first contestant to be eliminated. Simpson said it was unfair that she had far less time to prepare than fellow sing-off contestant Shelley Smith, claiming "They set me up to go out in the first week". It was reported that Cowell was planning to axe the flash vote after The X Factor was heavily beaten by Strictly Come Dancing in the ratings for the second live show. The flash vote was not used in week 4 due to a performance at the start of the show by Nile Rodgers and Chic, and was not used again in week 5. A source from the show said, "at the moment it is not scheduled to return". The flash vote was not used again after week 3.

Before judges' houses, urban act Code 4 had to drop one of their members, Mark Wyman, after it emerged that he had a criminal record, and a spokesman for The X Factor said, "Unfortunately due to problems in getting a visa Mark was unable to travel to Judges' Houses in America, meaning that he ended up having to leave the band to carry on in the competition as a three piece." Code 4 did not make it to the live shows. Three-piece band Rough Copy also had to lose member Kazeem "Kaz" Ajobe before the six-chair challenge due to visa problems. The same had happened to the group in series 9, but this year the other two members, Sterling Ramsay and Joey James, continued without Ajobe and advanced to judges' houses as a duo. Fans questioned the events, and the extent to which ITV wanted to resolve them, saying they had a year to get a visa, and Barlow could have stayed in the United Kingdom, the latter sentiment to which Barlow admitted to Ajobe he should have done during the judges' houses episodes. Barlow put Rough Copy through to the live shows and Ajobe was allowed to rejoin the band. Furthermore, just after Ajobe was reinstated, controversy was caused when his criminal past was publicised. Ajobe responded by stating: "I've done things I am not proud of. I haven't been an angel but I am a changed man now."

There was criticism over SeSe Foster of Miss Dynamix being allowed to compete in the show, because she was five months pregnant when the live shows began. Some viewers also thought it was unfair that Miss Dynamix got an automatic bye to the next week when Foster collapsed before the second live show. Foster dismissed this, saying that she "deserve[s] a shot at a better life" and insisted her collapse was not related to her pregnancy. The following week, Miss Dynamix were eliminated after losing the flash-vote and the sing-off to Hannah Barrett. Following this, Barlow stated that he felt that all public hopes of the group continuing in the competition had ended with their absence in week 2, despite him previously hoping that Foster's collapse would have gained more sympathy for them from the public.

Judges' comments
Some viewers were shocked by a comment made by Osbourne following 16-year-old Nicholas McDonald's performance of "She's the One" during the second live show. As McDonald got to the end of the song, a female backing dancer walked towards him and he kissed her cheek after the song finished. Despite the minimum age of sexual consent in the United Kingdom and the Crown Dependencies standing at 16, Osbourne then said to McDonald, who was 16 and therefore legal, "Who on earth was that piece of whatever next to you? That paedophile. You're only 16. You can't be doing that. That's a disgrace ITV." She was later spoken to by producers, but Walsh defended her, saying "She meant nothing wrong by it. We all say things we shouldn't and X Factor is not scripted." The dancer declined to comment, but a source close to her said that she was embarrassed by Osbourne's comment.

Guest performances
Ofcom received around 200 complaints about Lady Gaga's performance, including her costume and lyrics, during the third results show on 27 October 2013. ITV received 60 complaints directly. Lady Gaga wore nude-coloured underwear and her lyrics included "do what you want with my body". A spokeswoman for ITV said, "We do not believe Lady Gaga's performance was inappropriate for the family audience of The X Factor results show, which has an established tradition of featuring performances from the biggest music stars. Lady Gaga is well known for her highly individual performance style." Ofcom said, "We will assess all the complaints received on this issue before deciding whether to investigate."

Robin Thicke's performance, which featured a large number of scantily-clad female dancers, also received a total of 317 complaints. On 16 December, both Gaga and Thicke were cleared of any wrongdoing, with an Ofcom spokesman stating, "We assessed the complaints and concluded there were no grounds to investigate."

Final
There were technical problems during Sam Bailey's duet performance with Scherzinger, when Jedward's voices could be heard as they completed a microphone test. The duet was panned by viewers who accused Scherzinger of being "selfish" by singing the "best" lines and notes of the song.
