Epic Records is a subsidiary of Sony Music Group and has had great commercial success by distributing albums like Michael Jackson's Thriller, the best selling album of all time. Sony Music Group uses horizontal integration to own other record labels and distribution companies. They promote artists through social media, music videos on sites like YouTube, and by making music available across streaming and download platforms. A smaller label like XL Recordings, which distributes Adele's albums, also relies on digital distribution and social media to reach a large audience.
