Up tenfold from 2010 figure.
Juniper Research's latest report claims mobile advertising revenues for mobile games will increase tenfold between 2010 and 2015.
The company estimates that ad-spend in mobile games was $87 million last year, but will rise to $894 million by 2015.
Juniper cites Angry Birds on Android, as well as Fishlabs' iPhone advergames for Barclaycard and Volkswagen, as current examples of successful ad-supported games.
"Angry Birds has been a huge hit over the last year on the iPhone since its launch; but arguably its relative impact, in terms of downloads, has been bigger on Getjar and, more recently, on Android Market, as a result of offering the game free with ads," says the report's author Daniel Ashdown.
"Users get a great game for free, but advertisers get significant product/brand exposure; the same is true of mobile games as marketing tools."
However, Juniper thinks revenues from in-app payments and pay-per-download purchases will still be ten times higher than advertising revenues for mobile games in 2015.
