The band decided on its title as each of the album's nine tracks were written as a group. The album cover depicts the shapes from a Shape-O, a children's toy made by Tupperware. Mike Rutherford referred to this album as his favorite Genesis album.[2] According to AllMusic, the album established that Genesis were "now primarily a pop band", although "art rock functions as coloring to the pop songs". Genesis was a commercial success upon its release. The album reached No. 1 in the UK and No. 9 in the U.S., where it sold over 4 million copies. Five singles were released between 1983 and 1984, with "Mama" being the band's highest-charting single in the UK at number 4. In 2007, Genesis was reissued with a new stereo and 5.1 surround sound mix as part of the band's box set, Genesis 1983–1998.
