The search research firm Juniper Research has lowered the prediction for adult mobile service revenues in 2008 to $2.2 billion i.e. 3.5% lower than the analyst had previously project.

The analyst predicts that the worldwide mobile adult market will hit $4.9 billion by 2013, with a large increase coming from video chat services which are predicted to surpass $1 billion in 2011, with low penetration being offset by high spending levels—in many markets averaging several hundred dollars per user per annum.

Some countries like Indonesia & Switzerland are tightening laws governing adult content, but in Europe and Latin America it’s becoming far more widespread.

Western Europe will remain the biggest market, followed by the Far East.
