Paul Gambaccini concludes his celebration of 60 years of British chart action.

The pop chart has always been viewed by record companies as the most effective way of advertising their product. Consequently, they have tried to manipulate it by both fair means and foul.

The programme examines the techniques that have been used over the decades to create a hit - 'buying in', discounting, coloured vinyl, remixes, different formats and the practice of winning airplay months ahead of release date.

The impact of download sales and the decline of physical product sales have been significant factors since 2004. Downloading has put control of the charts back in the hands of the consumer.

But does this mean that the chart is now much more accurate as a measure of the popularity of songs? And does anyone care about chart positions anymore?
