While revenues of ad-supported mobile content revenues will top $1 billion by 2015, mobile video will lead the way in growth, eMarketer predicts. US-based ad revenues from mobile video reached just $37.5 million in 2011, but eMarketer predicts that advertisers will spend $213.6 million on placements by 2015.
Still, those revenues will be lower than for mobile games at $269.1 million for mobile games in 2015, and $591.5 million for mobile music. At present, mobile music leads the pack with a $181.4 million ad spend in 2011—73.9% of the total, and a projected 79.3% in 2015. eMarketer projects for 2012 that 29.9% of mobile content revenues, or $1.07 billion, will come from advertising support.
