The Billboard charts tabulate the relative weekly popularity of songs or albums in the United States. The results are published in Billboard magazine. The two primary charts – the Hot 100 (top 100 singles) and the Billboard 200 (top 200 albums) – factor in airplay, as well as music sales in all relevant formats.

On January 4, 1936, Billboard magazine published its first music hit parade. The first Music Popularity Chart was calculated in July 1940. A variety of song charts followed, which were eventually consolidated into the Hot 100 by mid-1958. The Hot 100 currently combines single sales, radio airplay and digital downloads.

All of Billboard's charts use this basic formula. What separates the charts is which stations and stores are used – each musical genre having a core audience or retail group. Each genre's department at Billboard is headed up by a chart manager, who makes these determinations.

For many years, a song had to be commercially available as a single to be considered for any of Billboard's charts. At the time, instead of using SoundScan or BDS, Billboard obtained its data from manual reports filled out by radio stations and stores. According to the 50th Anniversary issue of Billboard, prior to the official implementation of Nielsen SoundScan tracking in November 1991, many radio stations and retail stores removed songs from their manual reports after the associated record labels stopped promoting a particular single. Thus songs fell quickly after peaking and had shorter chart lives. In 1990, the country singles chart was the first chart to use SoundScan and BDS. They were followed by the Hot 100 and the R&B chart in 1991. Today, all of Billboard's charts use this technology.

Before September 1995, singles were allowed to chart in the week they first went on sale based on airplay points alone. The policy was changed in September 1995 to only allow a single to debut after a full week of sales on combined sales and airplay points. This allowed several tracks to debut at number one.

In December 1998, the policy was further modified to allow tracks to chart on the basis of airplay alone without a commercial release. This change was made to reflect the changing realities of the music business. Previous to this, several substantial radio and MTV hits had not appeared on the Billboard chart at all, because many major labels chose not to release them as standalone singles, hoping their unavailability would spur greater album sales. Not offering a popular song to the public as a single was unheard of before the 1970s. The genres that suffered most at the time were those that increasingly impacted pop culture, including new genres such as trip hop and grunge. Among the many pre-1999 songs that had ended up in this Hot 100 limbo were The Cardigans' "Lovefool", Natalie Imbruglia's "Torn", Goo Goo Dolls' "Iris", OMC's "How Bizarre", Sugar Ray's "Fly" and No Doubt's "Don't Speak".

Starting in 2005, Billboard changed its methodology to allow paid digital downloads from digital music stores such as iTunes to chart with or without the help of radio airplay.

A variety of charts[link]

Originally, Billboard had separate charts for different measures of popularity, including disk jockey playings, juke box song selection, and best selling records in retail stores. A composite standing chart that combined these gradually grew to become a top 100, the ancestor of the current Hot 100 chart. The juke box chart ceased publication after the June 17, 1957 issue, the disk jockey chart, after the July 28, 1958 issue, and the best seller chart, after the October 13, 1958 issue. The July 28, 1958 issue was also the last issue that called the composite chart the Top 100; the following week began the Hot 100.

Currently, Billboard publishes many different charts, with the Hot 100 and Billboard 200 being the most famous. Billboard also has charts for the following music styles: rock, country, dance, bluegrass, jazz, classical, R&B, rap, electronic, pop, Latin, Christian music, comedy albums, catalog albums, and even ringtones for mobile (cell) phones. In 2009 Billboard partnered with MetroLyrics to offer top 10 lyrics for each of the charts.

At year's end[link]

At the end of each year, Billboard tallies the results of all of its charts, and the results are published in a year-end issue and heard on year-end editions of its American Top 40 and American Country Countdown radio broadcasts, in addition to being announced in the press. Between 1991 and 2006, the top single/album/artist(s) in each of those charts was/were awarded in the form of the annual Billboard Music Awards, which were annually held in December until the awards went dormant in 2007 (plans for a new version of the awards in 2008 fell through). The awards returned in May 2011. The year-end charts cover a period from the first week of December of the previous year to the last week of November of the respective year.[1]^{[dead link]}

In December 2010, Billboard announced a new chart titled Social 50, which ranks the most active artists on the world's leading social networking sites. The Social 50 chart tallies artists' popularity using their weekly additions of friends/fans/followers, along with weekly artist page views and weekly song plays on Myspace, YouTube, Facebook, Twitter and iLike.^[3]

In January 2011, Billboard introduced another chart called Uncharted, which lists new and developing artists, who are yet to appear on any major Billboard chart, "...regardless of their country of origin."^[4] The ranking is based on the views and fans on social networking websites like Myspace and Facebook. To appear on Uncharted, the artists must be registered Myspace Music artists, and should not have appeared on any major Billboard charts before.^[4]
