Background: Top of the Pops, also known as TOTP, is a British music chart television programme, made by the BBC and originally broadcast weekly between 1 January 1964 and 30 July 2006. It was traditionally shown every Thursday evening on BBC One, except for a short period on Fridays in mid-1973 before being again moved to Fridays in 1996 and then to Sundays on BBC Two in 2005. Each weekly programme consisted of performances from some of that week's best-selling popular music artists, with a rundown of that week's singles chart. Additionally, there was a special edition of the programme on Christmas Day (and usually, until 1984, a second such edition a few days after Christmas), featuring some of the best-selling singles of the year.
Context: From 1967, the show had become closely associated with the BBC radio station Radio 1, usually being presented by DJs from the station, and between 1988 and 1991 the programme was simulcast on the radio station in FM stereo. However, during the last few years of the 1980s the association became less close, and was severed completely (although not permanently) in a radical shake-up known as the 'Year Zero' revamp.  Following a fall in viewing figures and a general perception that the show had become 'uncool' (acts like The Clash had refused to appear in the show in previous years), a radical new format was introduced by incoming executive producer Stanley Appel (who had worked on the programme since 1966 as cameraman, production assistant, director and stand-in producer) in October 1991, in which the Radio 1 DJs were replaced by a team of relative unknowns, such as Claudia Simon and Tony Dortie who had previously worked for Children's BBC, 17-year-old local radio DJ Mark Franklin, Steve Anderson, Adrian Rose and Elayne Smith, who was replaced by Femi Oke in 1992. A brand new theme tune ('Now Get Out Of That'), title sequence and logo were introduced, and the entire programme moved from BBC Television Centre in London to BBC Elstree Centre in Borehamwood.  The new presenting team would take turns hosting (initially usually in pairs but sometimes solo), and would often introduce acts in an out-of-vision voiceover over the song's instrumental introduction. They would sometimes even conduct short informal interviews with the performers, and initially the Top 10 countdown was run without any voiceover. Rules relating to performance were also altered meaning acts had to sing live as opposed to the backing tracks for instruments and mimed vocals for which the show was known. To incorporate the shift of dominance towards American artists, more use was made of out-of-studio performances, with acts in America able to transmit their song to the Top of the Pops audience "via satellite". These changes were widely unpopular and much of the presenting team were axed within a year, leaving the show hosted solely by Dortie and Franklin (apart from the Christmas Day editions, when both presenters appeared) from October 1992, on a week-by-week rotation.
Question: What was the Year Zero revamp?
Answer: during the last few years of the 1980s the association became less close, and was severed completely (although not permanently) in a radical shake-up known as the 'Year Zero' revamp.

Background: Mary Teresa Slaney (formerly Tabb, nee Decker; born August 4, 1958) is a retired American middle-distance runner. During her career, she won gold medals in the 1500 meters and 3000 meters at the 1983 World Championships, and was the world record holder in the mile, 5000 meters and 10,000 meters. In total, she set 17 official and unofficial world records, including being the first woman in history to break 4:20 for the mile. She also set 36 US national records at distances ranging from 800 meters to 10,000 meters, and has held the US record in the mile, 2000 meters and 3000 meters since the early 1980s, while her 1500 meters record stood for 32 years.
Context: Decker was heavily favored to win a gold medal in the 3000 meters run at the 1984 Summer Olympics, held at Los Angeles. In the final, Zola Budd, representing Great Britain, had been running barefoot side by side with Decker for three laps and moved ahead. In an attempt to put pressure on Budd, Decker remained close by in a crowded space. Decker stood on Budd, then shortly after, collided with the barefoot runner and fell spectacularly to the curb. As a result, Mary Decker did not finish the race, which was won by Maricica Puica of Romania (Budd finished seventh). Decker was carried off the track in tears by her boyfriend (and later, husband), British discus thrower Richard Slaney. At a press conference she said that Budd was to blame for the collision. While it is generally the trailing athlete's responsibility to avoid contact with the runner ahead, it is also an accepted convention among most distance runners that the leader be a full stride ahead before cutting in. Track officials initially disqualified Budd for obstruction, but she was reinstated just one hour later once officials had viewed films of the race. Despite being behind Budd, Decker's claim that Budd had bumped into her leg was supported by a number of U.S. sports journalists, and Budd was hounded constantly in the press as a result, receiving a number of death threats. The claim was never accepted by the director of the games or the IAAF.  Decker and Budd next met in July 1985, in a 3000 meters race at Crystal Palace National Sports Centre in London, England. Decker won the race, and Budd finished in fourth place. After the race, the two women shook hands and made up. Decker later went on record as claiming that she was unfairly robbed of the LA 3000 meters gold medal by Budd, but said many years after the event "The reason I fell, some people think she tripped me deliberately. I happen to know that wasn't the case at all. The reason I fell is because I am and was very inexperienced in running in a pack."  Decker had a successful 1985 season, winning twelve mile and 3000 meters races in the European athletics calendar, which included a new official world record for the women's mile of 4:16.71 in Zurich (Natalya Artyomova's 4:15.8 in 1984, not being ratified by the IAAF). Since that race in 1985, her time has only been bettered on four occasions. That race in Zurich also matched her with both of the other principle athletes from the Olympic race, Slaney vanquishing both Puica and Budd who themselves ran times that until July 9, 2017 also ranked in the top 10 of all time.  She sat out the 1986 season to give birth to her only child, daughter Ashley Lynn (born May 30, 1986), but missed the 1987 season due to injury. She qualified for the 1988 Summer Olympics in Seoul, South Korea, but failed to win a medal. She did not qualify for the 1992 Games.
