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. The programme was shown every Thursday evening on BBC One, except for a short period on Fridays in mid-1973 before being again moved to Fridays at 7:30 pm 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.
