The Official Charts Company (previously known as the Chart Information Network (CIN) and The Official UK Charts Company, legally known as The Official UK Charts Company Limited) is a British inter-professional organisation that compiles various "official" record charts in the United Kingdom, Ireland and France. In the United Kingdom, its charts include ones for singles, albums and films, with the data compiled from a mixture of downloads, purchases (of physical media) and streaming. The OCC produces its charts by gathering and combining sales data from retailers through market researchers Kantar, 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.
