The Publicis Groupe media agency had previously forecast a flat 2013 for the UK’s biggest advertising medium, with 3.4% growth for the entire ad market.
It has also downgraded its 2013 overall market growth prediction to 2.5%, after trimming every medium except cinema.
This year’s growth has also been downgraded from 2.2% to 1.6%. The post-Olympic performance of press has been troubling, with a 10% drop in October, and the agency is now expecting the press market to drop 7.3% this year.
Digital is not unscathed, with its 2012 growth forecast reduced from 11% to 10.5% and 2013 reduced from 9.9% to 9.2%.
The agency said: "Video continues to be the major driver behind digital growth; in H1 2012 it was up 43% year on year.
"Social media continues to grow aggressively as well, but we are expecting Google to overtake Facebook to become the market leader in terms of revenue."
