The UK Singles Chart is currently compiled by The Official UK Charts Company (OCC) on behalf of the British record industry. The chart week runs from Sunday to Saturday, with the chart being printed in Music Week magazine, and published online at Yahoo! Music UK (formerly Dotmusic)charts.html" target="_blank">http://uk.launch.yahoo.com/c/uk/single_charts.html. Around 6,500 UK retail outlets contribute sales data, as well as several online digital download stores. Unlike in the _USA, no airplay statistics are used for the official UK Singles Chart. Most UK singles are released in record shops on a Monday.
The main chart contains the top 200 singles combining record sales and downloads 50/50, of which the Top 75 is generally considered the official chart - though only the top 40 is commonly reported to the wider public. The Top 75 singles and albums charts, including songwriter, producer, publisher and label credits, plus a wide selection of other sales charts, are published each week in Music Week magazine. The complete charts, including the Top 200 Singles and Top 200 Artist Albums, are published by independent chart newsletter ChartsPlus on Wednesdays.
According to the Official UK Charts Company's statistics, as of 17 February 2008, 1,068 singles had topped the UK singles chart. The precise number is debatable due to the profusion of different competing charts during the 50s, 1960s, 1970s and 1980s, although the usual list used is that endorsed by the Guinness Book of British Hit Singles and subsequently adopted by The Official UK Charts Company.
The Top 40 is currently, and always has been, revealed first by BBC Radio 1, even before it is posted on the OCC's own website. Radio 1 broadcasts the Top 40, in reverse order, on Sundays from 4pm to 7pm. Mark Goodier and Bruno Brookes are famous for having been the presenters of this chart show for many years. Since October 2007, Fearne Cotton and Reggie Yates have presented the chart show. Cotton is the first ever permanent female presenter of the Official Chart Show. A rival chart, hit40uk, which is based on sales and airplay, is broadcast on more than 100 commercial radio stations.
