By the end of 2013 there will be more iOS and Android devices in use than PCs. Google is using Plus and Android to reposition itself to take advantage of this, extending its reach and capturing far more behavioural data

We forecast UK online advertising to grow by 8% CAGR to £5.1 billion by 2014, representing approx. 33% of total advertising spend, overtaking press

Growth in spend on social media and video networks will push online display to just over £1 billion by 2014; whilst classifieds will grow to £840 million
