Last time we talked about how e-book dominance is inevitable, and how the US is leading the charge. Pretty much everyone pegs the UK market as being around a year behind the US. However, latest figures show the gap may be closing. The Publishers Association (PA) has revealed staggering e-book growth in 2010. In figures just released this morning, UK e-book sales – across all categories – have grown to over £16m ($26m), growing by over 300% on 2009 levels. By end of December 2010, they had captured 6% of the market.
