Question: When was The Five Doctors produced?
About the article "Doctor Who", section "Charity episodes".

Candidate passages:
In May 1962, a meeting of doctors passed a resolution vowing that physicians would close their practices if and when Medicare came into force.
"Keep Our Doctors" committees were established throughout the province and a campaign, backed by the "Regina Leader-Post" was undertaken with warnings that most doctors would leave the province if socialized medicine were introduced.
On July 1, 1962, the doctors strike began and approximately 90% of the province's doctors shut their offices. 
The GMC is now empowered to license and regularly revalidate the practice of doctors in the UK.
When the licensing scheme was introduced in 2009, 13,500 (6.1%) of registered doctors chose not to be licensed.
Unlicensed but registered doctors are likely to be non-practising lecturers, managers, or practising overseas, or retired.
Whereas all registered doctors in the UK were offered a one-off automatic practise license in November 2009, since December 2012 no license will be automatically revalidated, but will be subject to a revalidation process every five years.
No doctor may now be registered for the first time without also being issued a license to practice, although a licensed doctor may give up their licence if they choose.
No unlicensed but registered doctor in the UK is subject to revalidation.
However, unlicensed but registered doctors in the UK are still subject to fitness-to-practice proceedings, and required to follow the GMC's good medical practice guidance. 
"Doctors" is produced by BBC Birmingham and is screened on BBC One, with the first episode broadcast on 27 March 2000.
It was created by Chris Murray, with Mal Young developing it and Carson Black the original producer.
The show has been shown at lunchtime since its inception, originally at 12.30pm as a lead-in to the BBC's "One O'Clock News".
After it was temporarily moved to allow for extended news coverage of the September 11th 2001 attacks, its regular slot changed to 2:10 pm, following directly after "Neighbours", after ratings rose to a 25% audience share.
When the BBC lost "Neighbours" to "Channel 5" in January 2008, it moved into the Australian soap's old slot of 1:45pm.
For a brief trial period in Summer 2000, selected episodes from the first series were shown on Fridays at 7 pm and from 16 February 2009, the show began transmitting in high definition on BBC HD at 4:00pm the same day.
"Doctors" was originally produced and broadcast in blocks of episodes, ranging from blocks of 40 to 130 episodes in the first three years.
For example, from season five in 2002 until January 2007, "Doctors" took lengthy breaks in transmission over the Summer, usually for six weeks, to accommodate the length of transmission.
However, the series' audience has developed and increased, prompting the BBC to commission "Doctors" as a year-round continuing series.
Currently, the show breaks in the summer for the Wimbledon Tennis matches held for two weeks, over Christmas and Easter period and for bank holidays.
On 26 March 2010, "Doctors" celebrated its 10th Anniversary and 1800th episode.
Under the title "Decade of Doctors", the BBC aired five-minute programmes about the show after each day's episode during the anniversary week.
On 16 February 2011, "Doctors" aired its 2,000th episode, "Quarantine", which was extended and ran for 60 minutes.
From 17 September 2012 for 5 days, special red button episodes aired after the regular show, focusing on the conclusion of the Harrison Kellor storyline, exploring Elaine Cassidy and her dealing with Harrison's change of plea for Lauren Porter's murder. 
The Five Doctors is a special feature-length episode of the British science fiction television series "Doctor Who", produced in celebration of the programme's 20th anniversary.
It had its world premiere in the United States, on the Chicago PBS station WTTW and various other PBS member stations on 23 November 1983, the anniversary date.
It was transmitted in the United Kingdom two days later (25 November).
The episode aired after the conclusion of the 20th season to celebrate the 20th anniversary.
It saw Patrick Troughton and Jon Pertwee reprise their roles of the Second and Third Doctors respectively, whilst Richard Hurndall portrayed the First Doctor, as the character's original actor William Hartnell had died since his last appearance on the show ten years previously in "The Three Doctors", and unused footage of Tom Baker was used to portray the Fourth Doctor, as he declined to appear.
