More than one billion people will own smartphones by 2016, according to the latest predictions by tech industry analyst Forrester. What’s more, consumers will be spending $56bn on mobile apps that year, the company predicts, with a call to arms for businesses. “Businesses should stop thinking about it as a small Web site on a tiny computer, and start thinking about mobile as being deeply embedded systems of engagement. That turns out to have huge implications,” says Forrester’s Ted Schadler. In separate ‘big numbers about consumer electronics’ news, NPD Group estimates that sales of consumer tech devices in the US alone reached nearly $144bn in 2011. 19.3% of that was PCs, 13.8% televisions, and 10.7% tablets and e-readers, followed by mobile phones (8.5%) and video game hardware (5.6%).
