This resulted in its share of digital ad revenues increasing from 17% to 25% in that time, according to the Interactive Advertising Bureau (IAB)’s Internet Advertising Revenue Report, compiled using information supplied by companies selling ads on the internet.

Total digital ad revenues increased 16% last year to reach a new high of $49.5bn. This marks the fifth consecutive year of double-digit growth for the industry. The report also shows that 2014’s fourth quarter numbers reached $14.2bn, a 17% rise from $12.1bn in the final quarter of 2013.

“Marketers clearly recognise that consumers are leading mobile-first lives and are investing their ad dollars accordingly,” said Randall Rothenberg, president and CEO, IAB.
