Billboard -LRB- stylized as billboard -RRB- is an American entertainment media brand owned by the Hollywood Reporter-Billboard Media Group , a division of Eldridge Industries . It publishes pieces involving news , video , opinion , reviews , events and style . It is also known for its music charts , including the Billboard Hot 100 and Billboard 200 , tracking the most popular singles and albums in different genres . It also hosts events , owns a publishing firm , and operates several TV shows . Billboard was founded in 1894 by William Donaldson and James Hennegan as a trade publication for bill posters . Donaldson later acquired Hennegen 's interest in 1900 for $ 500 .   In the 1900s , it covered the entertainment industry , such as circuses , fairs and burlesque shows . It also created a mail service for travelling entertainers . Billboard began focusing more on the music industry as the jukebox , phonograph and radio became commonplace . Many topics it covered were spun-off into different magazines , including Amusement Business in 1961 to cover outdoor entertainment so that it could focus on music . After Donaldson died in 1925 , Billboard was passed down to his children and Hennegan 's children , until it was sold to private investors in 1985 , and has since been owned by various parties .
