By early 1964, the Beatles were international stars, leading the "British Invasion" of the United States pop market, breaking numerous sales records, and inspiring Britain's cultural resurgence. They soon made their film debut with "A Hard Day's Night" (1964). From 1965 onwards, they produced records of greater complexity, including the albums "Rubber Soul" (1965), "Revolver" (1966) and "Sgt. Pepper's Lonely Hearts Club Band" (1967), and enjoyed further commercial success with "The Beatles" (also known as "the White Album", 1968) and "Abbey Road" (1969). Heralding the album era, their success elevated the album to be the dominant form of record consumption over singles; they also inspired a greater public interest in psychedelic drugs and Eastern spirituality, and furthered advancements in electronic music, album art and music videos. In 1968, they founded Apple Corps, a multi-armed multimedia corporation that continues to oversee projects related to the band's legacy. After the group's break-up in 1970, all four members enjoyed success as solo artists. Lennon was shot and killed in 1980, and Harrison died of lung cancer in 2001. McCartney and Starr remain musically active.
