Billboard charts
The Billboard charts tabulate the relative weekly popularity of songs and albums in the United States and elsewhere. The results are published in Billboard magazine. Billboard biz, the online extension of the Billboard charts, provides additional weekly charts,[1] as well as year-end charts.[2] The two most important charts are the Billboard Hot 100 for songs and Billboard 200 for albums, and other charts may be dedicated to a specific genre such as R&B, country, or rock, or they may cover all genres. The charts can be ranked according to sales, streams, or airplay, and for main song charts such as the Hot 100 song chart, all three data are used to compile the charts.[3] For the Billboard 200 album chart, streams and track sales are included in addition to album sales.[4]
The weekly sales and streams charts are monitored on a Friday-to-Thursday cycle since July 2015; previously it was on a Monday-to-Sunday cycle. Radio airplay song charts, however, follow the Monday-to-Sunday cycle (previously Wednesday-to-Tuesday).[5] The charts are released each Tuesday with an issue date the following Saturday.
Other charts[edit]
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.[45]
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."[46] The ranking is based on the views and fans on social networking websites like Myspace and Facebook. It has since been discontinued.
In May 2014, after the Korea K-Pop Hot 100 chart was discontinued in the U.S., the Billboard K-Town column continued to provide chart information for K-pop artists on all Billboard charts.[47][48]
The Artist 100 debuted in July 2014.
In June 2019, Billboard launched the Top Songwriters Chart and the Top Producers Chart, based on weekly activity on the Hot 100 and other "Hot" genre charts.[49]
In October 2021, Billboard launched the Hot Trending Songs charts, utilising real-time music-related trends and conversations on Twitter.[50]
