The UK Album Chart is a weekly record chart which for most of its history was based on album sales from Sunday to Saturday in the United Kingdom. Since July 2014 it has also incorporated streaming data, and from 10 July 2015 has been based on a Friday to Thursday week. The chart was founded in 1956 and began with just a top 5 being unveiled; this was extended to a top 10 from November 1958 onwards. The first album to top the chart was Songs for Swingin' Lovers! by Frank Sinatra.
