The Official Charts Company, also referred to as Official Charts (previously known as the Chart Information Network (CIN) and The Official UK Charts Company) is a British inter-professional organisation that compiles various "official" record charts in the United Kingdom, including the UK Singles Chart, the UK Albums Chart, the UK Singles Downloads Chart and the UK Album Downloads Chart, as well as genre-specific and music video charts. The OCC produces its charts by gathering and combining sales data from retailers through market researchers Millward Brown, and claims to cover 99% of the singles market and 95% of the album market, and aims to collect data from any retailer who sells more than 100 chart items per week.[1] In 2017, the OCC made a deal with the Irish Recorded Music Association (IRMA) to compile the Irish Singles Chart, Irish Albums Chart and other Irish charts on behalf of IRMA.
