Blackout is the fifth studio album by American recording artist Britney Spears, released by Jive Records on October 26, 2007. Spears began working on this album as early as February 2006, exploring into electropop, synthpop and techno. The album has a more R&B/urban sound and recording with new producers such as Danja. Blackout was her first studio album in four years since 2003's In the Zone and is the first time Spears is the executive producer of one of her albums. The album's title refers to "blacking out negativity and embracing life fully". The songs on the album are thematically focused on sex, love and Spears' relationship–struggle with the media.

Blackout debut at number two on the Billboard 200, becoming her first, and so far only studio album not to debut at number one, due to changes in Billboard structuring at the time. This caused controversy with some in the media, as the changes were only announced and subsequently put into effect half-way through Blackout's opening week. According to the IFPI, the album was 32nd in terms of units shipped by the end of 2007.
