Digital activities contribute an average of 12 per cent of revenues at companies that are members of the UK Association of Online Publishers, according to the latest annual survey of the organisation's members.
AOP, which represents around 160 of the UK's largest online content producers — including the digital divisions of newspapers, broadcasters and magazine publishers — found that advertising accounts for 75 per cent of online revenue at the 57 member companies that competed its survey.
Display advertising and sponsorship contributes 59 per cent of the publishers' online revenues, with classifieds accounting for 16 per cent.
However, a growing number of AOP members are charging for their content, the survey found. Forty-six per cent of AOP members reported charging for content, up from 37 per cent in 2006.
Paid-for content, including syndication services, contributed 12 per cent of AOP members' revenues, representing an increase of 50 per cent in 2006.
In a statement, AOP chairman Simon Waldman, the director of digital strategy at Guardian Media Group, said: "This is a remarkable set of figures. 2006 was a year of spectacular digital growth, innovation and investment by the UK's media industry – and our forecasts show there is no sign of this letting up."
