The Billboard 200 is a ranking of the 200 highest-selling music albums and EPs in the United States, 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 outsold all others during at least one week.

The chart is based solely on sales (both at retail and digitally) of albums in the United States. The sales tracking week begins on Monday and ends on Sunday. A new chart is published the following Thursday with an issue date of the Saturday of the following week.

Normally new products are released to the American market on Tuesdays. Digital downloads are included in Billboard 200 tabulation, as long as the entire album is purchased as a whole. Albums that are not licensed for retail sale in the United States (yet purchased in the U.S. as imports) are not eligible to chart. A long-standing policy which made titles that are sold exclusively by specific retail outlets (such as Wal-Mart and Starbucks) ineligible for charting, was reversed on November 7, 2007, and took effect in the issue dated November 17.

Mariah Carey (born March 27, 1970) is an American singer, songwriter, record producer, and actress. She made her recording debut in 1990 under the guidance of Columbia Records executive Tommy Mottola, and released her self-titled debut studio album, Mariah Carey. The album went multi-platinum and spawned four consecutive number one singles, on the U.S. Billboard Hot 100 chart. Following her marriage to Mottola in 1993, a series of hit records, including Emotions (1991), Music Box (1993) and Merry Christmas (1994), established her position as Columbia's highest-selling act. Daydream (1995), made music history when the second single, "One Sweet Day" a duet with Boyz II Men, spent a record sixteen weeks on top of the Billboard Hot 100, and remains the longest running number one song in US chart history. During the recording of the album Carey began to deviate from her pop background, and slowly traversed into R&B and Hip-hop. After her separation from Mottola, this musical change was evident with the release of Butterfly (1997).

Janet Damita Jo Jackson (born May 16, 1966) is an American recording artist and actress. Known for a series of sonically innovative, socially conscious and sexually provocative records, as well as elaborate stage shows, television and film roles, she has been a prominent figure in popular culture for over 25 years. The youngest child of the Jackson family, she began her career with the variety television series The Jacksons in 1976 and went on to appear in other television shows throughout the 1970s and early 1980s, including Good Times and Fame.

After signing a recording contract with A&M in 1982, she came to prominence following the release of her third studio album Control (1986). Her collaborations with record producers Jimmy Jam and Terry Lewis incorporated elements of rhythm and blues, funk, disco, rap, and industrial beats, which led to crossover appeal in popular music. In addition to receiving recognition for the innovation in her records, choreography, music videos, and prominence on radio airplay and MTV, she was acknowledged as a role model for her socially conscious lyrics.
