Internet shopping is now more popular in the U.K. than the other countries surveyed by Ofcom. The regulator said shopping online is being “increasingly driven” by the use of mobile devices. More than a fifth (23.1 percent) of U.K. smartphone users used their device to visit retail websites in the whole of 2011 — which Ofcom said is the highest level out of the five largest European countries. Germany was second with 22.6 percent. Ofcom also notes that U.K. consumers have broken the £1,000-a-year “spend barrier” on Internet shopping — once again, more than any other country covered by the research. In 2011, the per-head spending on e-commerce was £1,083 in the UK, up 14 percent from 2010′s £950. Australia spent the second highest at £842, with Sweden third at £747, according to Ofcom.
