<P> When the programme's format changed in November 2003, it concentrated increasingly on the top 10 . Later, during the BBC Two era, the top 20 was regarded as the main cut - off point, with the exception made for up and coming bands below the top 20 . Singles from below the top 40 (within the top 75) were shown if the band were up and coming or had a strong selling album . If a single being performed was below the top 40, just the words "New Entry" were shown and not the chart position . </P> <P> The show was originally intended to run for only a few programmes but lasted over 42 years, reaching landmark episodes of 500, 1,000, 1,500 and 2,000 in the years 1973, 1983, 1992 and 2002 respectively . </P> <P> Top of the Pops was first broadcast on Wednesday, 1 January 1964 at 6: 35 pm . It was produced in Studio A on Dickenson Road in Rusholme, Manchester . </P> <P> DJ Jimmy Savile presented the first show live from the Manchester studio (with a brief link to Alan Freeman in London to preview the following week's programme), which featured (in order) the Rolling Stones with "I Wanna Be Your Man", Dusty Springfield with "I Only Want to Be with You", the Dave Clark Five with "Glad All Over", the Hollies with "Stay", the Swinging Blue Jeans with "Hippy Hippy Shake" and the Beatles with "I Want to Hold Your Hand", that week's number one--throughout its history, the programme proper always (with very few exceptions) finished with the best - selling single of the week, although there often was a separate play - out track . </P>
