Dannii Minogue made a reference to Danyl Johnson's sexuality
The X Factor has prompted the most viewer complaints to media watchdog Ofcom so far in 2009, figures reveal.
The talent search attracted 5,975 complaints, with 4,000 relating to Dannii Minogue's remarks about contestant Danyl Johnson.
The 10th series of Big Brother, its celebrity spin-off and Britain's Got Talent all featured prominently.
Ofcom recorded its biggest volume of complaints - 64,996 - in 2007 due to the Shilpa Shetty racism row.
But the organisation said the amount of complaints fell in 2008 after the unprecedented public reaction to the incident on Celebrity Big Brother.
BBC One's Question Time programme made fifth place in the 2009 list due to the controversy surrounding BNP leader Nick Griffin's inclusion on the panel.

Coronation Street was the only soap opera to appear in the top 10, over issues including long-running character Ken Barlow's remarks about Easter which were seen as anti-Christian by some viewers.
Ofcom's chief executive Ed Richards said the body had seen an underlying trend towards an increase in complaints since it came into existence in 2004.
Speaking at the Culture and Media Select Committee, Mr Richards put it down to a rise in cable and satellite channels with "less well-established compliance" procedures and lower budgets.
"It was thought that people would become more comfortable with the idea there was a range of content," he said, but added there had been a "steady rise" in complaints.
Mr Richards said that "boundaries are well understood" by more established broadcasters, although some of their programmes have been criticised by viewers.
