Sales through Nielsen BookScan's Total Consumer Market (TCM), which covers over 90% of UK book retail and internet sales, for the 52 weeks ending 30th December 2006. Revenue for 2006 includes full-year sales for acquired companies (Hachette Livre includes Little, Brown; Random House Group includes BBC Books adult titles).
* Main growth figure represents 'like-for-like' growth (with acquired companies included in 2005 and 2006 sales). Therefore the percentage is not calculable from the displayed revenue totals. Figures in brackets show 'organic growth' (with acquired companies removed from the totals).
