King of the World was one of four albums to be written and produced by Edwards and Rodgers in 1980, the other three being Sister Sledge's Love Somebody Today, Chic's fourth studio album Real People and Diana Ross' multiplatinum selling Diana.

King of the World was first released on compact disc in 1996 by both East-West Music and Rhino Records. A remastered edition was issued by Warner Music France in 2006 including bonus tracks which are remixes dating from 1992 and the unreleased US promo version of "Your Love Is Good," whose instrumental can also be found on an outtake from Chic's 2010 box set "The Chic Organization" (there was also an alternate version that featured a piano break in place of the Chic guitar riffs). The latter also had been rerecorded by Sheila on numerous occasions.

An 18 CD box-set of all Sheila's recordings was released in 2006 and a new remix of "Spacer" was included. The "Freak Out - Respect to CHIC" remix using the original instrumental and vocal tracks. Sheila re-recorded "Spacer" only once in 1998 and six remixes were released.

The original American tapes have been digitally remastered for the first time and released on a deluxe edition in October 2008 by Warner Music France. It includes a 32-page booklet with exclusive interviews of Sheila and Nile Rodgers and unknown out-takes from the recording sessions. In 2013, the two reunited for the first time since the album was released to do a brief acoustic version of "Spacer."^[2]

The single "Spacer" was ranked at number eight among the top "Tracks of the Year" for 1979 by NME^[3] and was sampled more than twenty years later by the team behind Europop act Army of Lovers (including Alexander Bard) for the Swedish group Alcazar. This record by Alcazar was "Crying at the Discotheque" which reached Number 13 in the UK Singles Chart and which was one of three hits by Alcazar in the UK chart to have sampled a production by The Chic Organization.^[4] In 2020, Sophie Ellis-Bextor released a cover of "Crying at the Discotheque" as the lead single from her UK Top 10 album Songs from the Kitchen Disco, while Crew 7 & Jaques Raupé released a dance version of "Spacer" on the Kontor Records label.^[5]
