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 to convey the popularity of an artist or groups of artists. Sometimes, a recording act is remembered for its "number ones" that outperformed all other albums during at least one week. The chart grew from a weekly top 10 list in 1956 to become a top 200 list in May 1967, acquiring its existing name in March 1992. Its previous names include the Billboard Top LPs (1961–1972), Billboard Top LPs & Tape (1972–1984), Billboard Top 200 Albums (1984–1985), Billboard Top Pop Albums (1985–1991), and Billboard 200 Top Albums (1991–1992).
The American singer-songwriter Taylor Swift has released 11 original studio albums, 4 re-recorded albums, 5 extended plays (EPs), and 4 live albums. She has sold 114 million album-equivalent units worldwide, 51 million of which are certified in the United States. In terms of pure sales, she has tallied 46.6 million albums in the United States and 7 million albums in the United Kingdom. On the US Billboard 200, as of August 2024, she has accumulated 14 number-one albums—seven of which sold one million first-week copies, and 84 weeks at number one—more than any other solo act.
The Billboard Global 200 is a weekly record chart published by Billboard magazine. The chart ranks the top songs globally and is based on digital sales and online streaming from over 200 territories worldwide. First announced in mid-2019, it officially launched in September 2020.
Top Album Sales is a music chart published by Billboard magazine starting in May 1991, and has existed in its current form since December 2014. It is a weekly chart documenting the best-selling albums on a weekly basis in the United States. Up until December 2014, this had been documented by the Billboard 200 chart, but that chart was altered to factor in music streaming by accounting for album-equivalent units in its tallies to document the effect of the rise of music streaming outlet such as Apple Music and Spotify. Starting in the Top Album Sales chart's debut week of May 25, 1991, Billboard began tabulating charts with electronically monitored piece count information from Soundscan, now known as Luminate. During the week of December 6, 2014, the chart switched to a methodology that blends album sales with track equivalent album units and streaming equivalent album units. The Top Album Sales chart was created to preserve the older methodology of counting pure album sales.
