This thesis investigates not only The Beatles' influence on pop culture but on society as a whole. Moreover, it portrays the band members both as cultural inventors and inheritors. This means, the artistic achievements of the Fab 4 are critically assessed by constantly incorporating their own roots and influences. The paper focuses not only on mainstream culture but also on sub-cultural phenomena or less-known musicians that were similarly important for the development of pop culture and The Beatles themselves. However, The Beatles are still the most lasting and influential of all the artists discussed here. Their timelessness becomes obvious from the numerous musicians who still successfully release Beatlesque music today. Among the main findings of my research there is the fact that popular culture and its music in particular happen in cycles and are, today, of a highly derivative character; the same applies to other fields belonging to pop, such as clothing. Especially since the 1990s, Rock music and fashion have been mainly based on the combination of already existing stylistic patterns (in this context, the 1960s and the Fab 4 are the most overt point of reference), which is demonstrated by means of '90s Britpop bands. Besides Beatles-related literature, this thesis is based on rare articles archived in the British Library and interviews with acclaimed experts such as the English music journalist and Beatles-connoisseur Paolo Hewitt or people deriving from the band's actual inner circle; such was the case with Gordon Millings, son of Dougie Millings, the Beatles' tailor until '67. Hence, with such information, this thesis distinguishes itself from similar academic works and, moreover, it may contribute to establishing popular culture as a proper field of investigation within the academic context.
