In 1997, Japanese rock group Sharam Q, fronted by Tsunku, began auditions for a female vocalist. These auditions aired via the reality show Asayan, and resulted in Michiyo Heike being crowned winner. Tsunku, however, decided to give five of the runners-up, Yuko Nakazawa, Natsumi Abe, Kaori Iida, Asuka Fukuda and Aya Ishiguro, a chance to become a group in their own right.

With members John Lennon, Paul McCartney, George Harrison and Ringo Starr, they became widely regarded as the foremost and most influential act of the rock era. Rooted in skiffle, beat, and 1950s rock and roll, the Beatles later experimented with several musical styles, ranging from pop ballads and Indian music to psychedelia and hard rock, often incorporating classical elements and unconventional recording techniques in innovative ways. In the early 1960s, their enormous popularity first emerged as "Beatlemania", but as the group's music grew in sophistication, led by primary songwriters Lennon and McCartney, they came to be perceived as an embodiment of the ideals shared by the counterculture of the 1960s., A corporate group or group of companies is a collection of parent and subsidiary corporations that function as a single economic entity through a common source of control. The concept of a group is frequently used in tax law, accounting and (less frequently) company law to attribute the rights and duties of one member of the group to another or the whole. If the corporations are engaged in entirely different businesses, the group is called a conglomerate. The forming of corporate groups usually involves consolidation via mergers and acquisitions, although the group concept focuses on the instances in which the merged and acquired corporate entities remain in existence rather than the instances in which they are dissolved by the parent. The group may be owned by a holding company which may have no actual operations., , established in 1999, is the holding company at the head of a Japanese corporate group that supplies statistics and information on music and the music industry in Japan.
