LONDON: Internet advertising expenditure will continue to increase in the UK during the next five years, with paid search driving this trend.

Research firm Enders Analysis estimates web adspend should enjoy a compound annual growth rate of 8% to 2014, reaching £5.1bn ($8.1bn; $6.0bn).

This equates to a 33% market share.

Search advertising, a category dominated by Google, will take £3.1bn of revenues, due to what Enders Analysis said was the channel's "appeal and value to advertisers as a sales and lead generation tool".

Elsewhere, rising interest in social media and video networks could push display adspend to just over £1bn, with classified returns hitting £840m.

The on-going challenges facing newspapers and magazines mean overall online ad sales are set to leapfrog those of press ads by the end of the forecast period, Enders Analysis said.
