The UK Video Charts is a group of charts compiled by the Official Charts Company on behalf of The British Association for Screen Entertainment. The charts are based on weekly DVD, Blu-ray and, formerly, VHS sales in 6,500 retailers across the UK. It does not receive any airplay. The main chart combines the sales of all video sales in the UK and trades under the name of the Combined Video Chart. There are also charts for the sales of music videos (Music Video Chart) and children's videos, among others. All of the charts are published on the OCC's website.
