In 1995, Jackson merged his ATV Music catalog with Sony's publishing division creating Sony/ATV Music Publishing. Jackson retained half-ownership of the company, earned $95 million upfront as well as the rights to even more songs. He then released the double album HIStory: Past, Present and Future, Book I. The first disc, HIStory Begins, was a 15-track greatest hits album, and was later reissued as Greatest Hits – HIStory Vol. I in 2001, while the second disc, HIStory Continues, contained 15 new songs. The album debuted at number one on the charts and has been certified for seven million shipments in the US. It is the best-selling multiple-disc album of all-time, with 20 million copies (40 million units) sold worldwide. HIStory received a Grammy nomination for best album.
The first single released from the album was the double A-side "Scream/Childhood". "Scream" was a duet, performed with Jackson's youngest sister Janet. The single had the highest debut on the Billboard Hot 100 at number five, and received a Grammy nomination for "Best Pop Collaboration with Vocals".You Are Not Alone" was the second single released from HIStory; it holds the Guinness World Record for the first song ever to debut at number one on the Billboard Hot 100 chart. It was seen as a major artistic and commercial success, receiving a Grammy nomination for "Best Pop Vocal Performance". In late 1995, Jackson was rushed to a hospital after collapsing during rehearsals for a televised performance; the incident was caused by a stress related panic attack. "Earth Song" was the third single released from HIStory, and topped the UK singles chart for six weeks over Christmas 1995; it sold a million copies, making it Jackson's most successful single in the UK. The HIStory World Tour began on September 7, 1996, and finished on October 15, 1997. Jackson performed 82 concerts in 58 cities to over 4.5 million fans. The show, which visited five continents and 35 countries, became Jackson's most successful in terms of audience figures.
