Underlining their timeless appeal and unique status in music, The Beatles have broken multiple chart records around the world following the September 9, 2009 (9-9-09) CD release of their digitally re-mastered catalogue.
In the major music markets of North America, Japan and the UK, consumers purchased more than 2.25 million copies of The Beatles' re-mastered albums, individually and in two multiple-CD boxed sets, one in stereo and one in mono, during the first five days of release (excluding non-traditional retail outlets whose sales are not tracked by the chart compilers).
The Beatles' original UK studio albums were re-mastered by a dedicated team of engineers at Abbey Road Studios in London over a four year period, carefully maintaining the authenticity and integrity of the original analogue recordings. The result is the highest fidelity the catalogue has seen since its original release.
