Countdown was a long-running popular weekly Australian music television show broadcast by the Australian Broadcasting Corporation from 8 November 1974 until 19 July 1987. It was created by Executive Producer Michael Shrimpton, producer/director Robbie Weekes and record producer and music journalist Ian "Molly" Meldrum. Countdown was produced at the studios of the ABC in the Melbourne suburb of Ripponlea. Countdown was the most popular music program in Australian TV history. It was broadcast nationwide on Australia's government-owned broadcaster, the ABC and commanded a huge and loyal audience. It soon exerted a strong influence on radio programmers because of its audience and the amount of Australian content it featured. For most of the time it was on air, it also gained double exposure throughout the country by screening a new episode each Sunday evening, and then repeating it the following Saturday evening. The majority of performances on the show were lip synched. Molly Meldrum, the program's talent co-ordinator, began appearing on-air in 1975, presenting the Humdrum music news segment and conducting interviews. Molly soon became the "face" of Countdown. He appeared regularly on-air until 1986. Another attraction to the program was the local & international acts who would host an episode - usually performing as well. During the show, Molly would interview them or have a chat with them before the show went out with the number 1 single of the week.
