The popularity of Def Leppard in their homeland had significantly grown over the previous four years, and "Hysteria" topped the charts in Britain in its first week of release. The album was also a major success in other parts of Europe. In the US, however, the band initially struggled to regain the momentum of "Pyromania" that was lost from such a prolonged absence. The success of the album's fourth single, "Pour Some Sugar on Me" would propel the album to the top of the US "Billboard" 200 albums chart on 23 July 1988, nearly a year after its release - topping the chart three separate times for a combined total of six weeks. In the "Billboard" issue dated 8 October 1988, Def Leppard held the No. 1 spot on both the singles and album charts with "Love Bites" and "Hysteria", respectively.
