Total spending on mobile advertising in Britain surpassed the PC in the first half of this year. PC sales have now fallen for eight consecutive quarters, the longest decline in the history of the industry.
Statcounter said that in mature markets such as the US and the UK, the desktop still accounts for the majority of web pages, but the gap is shrinking dramatically, while the mobile web has long been more popular in countries such as India, where it now accounts for 75 per cent of pages.
The data excludes the use of apps such as Facebook and WhatsApp, which account for a significant proportion of mobile internet usage.
Aodhan Cullen, Statcounter's chief executive, warned that many small businesses and retailers have websites not designed for phones and tablets: "This should be a wake-up call especially for small businesses, sole traders and professionals."
