ZenithOptimedia has revised this year's forecast for advertising growth and expects the UK ad market to be up by almost 3 percent, MediaGuardian reported today.

In April the media agency predicted advertising in national newspapers to be flat, but now this sector could grow by 1.9 percent. It would be the first time since 2007 that British newspapers have shown an increase.

"The first five months have been pretty positive for print. Newspapers have spent a lot of time marketing themselves, such as the Sun during the World Cup, which has held up circulation. However the second half of the year does not look as strong for the newspaper advertising sector," Jonathan Barnard, head of publications at ZenithOptimedia, told MediaGuardian.

But newspapers, which saw an increase of 9.5 percent from January to May, were not the only ones to receive good news. The company also forecasts a raise of 7 percent in TV advertising and 4.6 percent in Internet ads, according to Marketing Week. However, radio ads are expected to decline by 2 percent.
