UK retail e-commerce sales are estimated to reach $51.8 billion (?28.1 billion) in 2011, up from $21.6 billion (?10.9 billion) in 2006, according to Verdict Research.

Verdict said online shopping has grown because broadband Internet access is now widely available in the UK at low cost. Major retailers have also made large investments in transactional Web sites.

Interactive Media in Retail Group (IMRG), as cited in a May 21, 2007, Financial Times article, also noted the rise in UK online spending. Looking at B2C e-commerce overall, the firm counted travel as the biggest online sector, followed by electronic products and apparel.

eMarketer's own projections for B2C e-commerce made in September 2006 included travel, event tickets and digital downloads, and estimated a total of $104.4 billion in 2010. Growth in online travel spending accounts for much of the difference from the Verdict numbers.
