The document discusses different aspects of the music industry including record labels, advertising, publicity, and promotion. The three major record labels that dominate the industry are Warner Music Group, Sony Music Entertainment, and Universal Music Group, collectively known as "THE BIG THREE". Advertising is paid for by the artist's record label and is used to directly sell and promote the artist's music. Publicity is generated by artists themselves and is not funded by record labels. Promotion involves artists partnering with companies owned by their record label or other organizations to mutually promote each other.
