The shift in ad spending reflects changing consumer behavior. Over a third of online Europeans are watching less TV because of their time online.
As for the ads, over a third of online consumers did not mind advertising as long as it was relevant to them.
eMarketer's own estimates cover Western Europe in particular. Advertisers will spend $7.5 billion online in 2007 in these countries, up 25% from $6.0 billion in 2006.
eMarketer Senior Analyst Lisa Phillips warned against making blanket assessments about the European market.
"Data for 'Europe' can cover wide or narrow areas, stretching from Iceland to Russia or just the UK to Germany," Ms. Phillips said. "Populations and attitudes vary just as widely. Europe as a region is far from homogeneous and advertising strategies must employ both national and pan-European elements."
