A new chart is published the following Tuesday with an issue post-dated to the Saturday of that week, four days later.

The Billboard 200 is a record chart ranking the 200 most popular music albums and EPs in the United States. It is published weekly by Billboard magazine. It is frequently used to convey the popularity of an artist or groups of artists. Often, a recording act will be remembered by its "number ones", those of their albums that outperformed all others during at least one week.

Currently, all music sales including singles, albums, digital download singles are on the same criteria. Unlike many countries, the highest certification is called "Million". Gold=100,000 and Silver=250,000
